feat(dashboard): add Tools & Apps page with liveness probes

New page at /tools listing all connected applications grouped by
category: Local Services (State Hub API, KeePassXC, pgAdmin, ops-bridge),
Source Control (Gitea), Identity/Auth (KeyCape, Authelia, privacyIDEA,
LLDAP), and Dev Tooling (Claude Code, uv). Local services show live
green/red/grey status dots via no-cors fetch probes.

+
+# Distributed Consistency — Multi-Machine State Sync
+
+## Problem
+
+The consistency checker assumes local workplan files are always the authoritative
+source of truth. This breaks in the primary development workflow:
+
+1. Implementation runs on **CoulombCore** (remote)
+2. Task status is written to the **state-hub DB** via ops-bridge tunnel
+3. The **workstation's local repo** is not updated (no `git pull`)
+4. Session close triggers `fix-consistency` on the workstation
+5. Checker reads stale local files (tasks still `todo`) and **regresses** DB
+   status — overwriting `done`/`in_progress` back to `todo`
+6. The dashboard shows progress, then silently reverts
+
+This is a design assumption in ADR-001 that breaks under multi-machine workflows.
+ADR-001 states the DB is rebuilt from files — but only holds when local files
+are always up to date.
+
+## Goal
+
+Eliminate false regressions and make `fix-consistency` safe to run regardless
+of local repo staleness. Three layers of defence:
+
+- **T01** (no-regress rule): Never allow fix-consistency to move a task
+  *backwards* in status. DB-ahead wins.
+- **T02** (pull gate): Detect and warn when local repo is behind its remote
+  before applying fixes.
+- **T03** (DB→file writeback): Write DB status back into workplan files and
+  commit, so files stay truthful and the multi-machine workflow naturally
+  converges.
+
+## Implementation Notes
+
+The status progression order for the no-regress rule:
+`todo → in_progress → blocked → done → cancelled`
+
+For the pull gate, `git fetch` is the only network call needed. No push, no
+merge — just detection. The fix mode should refuse or warn; check mode should
+always be allowed to report.
+
+For writeback (T03), `fix-consistency --fix` needs to:
+1. Detect tasks where DB status > file status
+2. Edit the workplan file (update the `status:` field in the task block)
+3. Stage and commit the change with a standard commit message
+
+Writeback must be idempotent and must not alter anything other than `status:`
+fields in task blocks.
+
+## Tasks
+
+### T01 — No-regress rule in consistency_check.py
+
+```task
+id: CUST-WP-0026-T01
+status: todo
+priority: high
+state_hub_task_id: "34a76f4c-ad3f-4780-ad62-1e788ceca224"
+```
+
+Modify `state-hub/scripts/consistency_check.py` so that `--fix` mode never
+regresses task status in the DB.
+
+**Status ordering:**
+```python
+STATUS_ORDER = {"todo": 0, "in_progress": 1, "blocked": 1,
+                "done": 2, "cancelled": 2}
+```
+
+In the C-11 fix path (file task found, DB task found, statuses differ):
+- If `STATUS_ORDER[db_status] >= STATUS_ORDER[file_status]`: skip the DB
+  update, emit a new check code **C-13** WARN:
+  `"DB task '{title}' is ahead of file (db={db_status}, file={file_status}) — skipped to prevent regression"`
+- If `STATUS_ORDER[db_status] < STATUS_ORDER[file_status]`: apply the update
+  as today (file is ahead, sync forward)
+
+New check code **C-13**: "DB task ahead of workplan file — regression
+prevented". Severity: WARN (not FAIL — this is expected in multi-machine
+workflows).
+
+Gate: `make test` must pass after this change.
+
+---
+
+### T02 — Git pull gate before --fix
+
+```task
+id: CUST-WP-0026-T02
+status: todo
+priority: high
+state_hub_task_id: "f9dbad4e-ba66-4e20-83ef-93b78c9e1590"
+```
+
+Add a remote-staleness check to `consistency_check.py` that runs at the start
+of `--fix` mode for each repo being checked.
+
+**Detection logic:**
+```bash
+git -C <repo_path> fetch --quiet origin 2>/dev/null
+LOCAL=$(git -C <repo_path> rev-parse HEAD)
+REMOTE=$(git -C <repo_path> rev-parse @{u} 2>/dev/null)
+# If LOCAL != REMOTE and REMOTE is reachable → repo is behind
+```
+
+If the repo is behind its remote tracking branch:
+- In `--fix` mode: emit **C-14** WARN and skip all write operations for that
+  repo. Print: `"Repo '{slug}' is behind remote — pull before fixing to avoid
+  clobbering remote progress"`.
+- In check-only mode: emit C-14 INFO (no-op, just informational).
+
+The `git fetch` must be best-effort — if the remote is unreachable (offline,
+ops-bridge down), skip the check silently rather than failing.
+
+New check code **C-14**: "Repo behind remote tracking branch". Severity: WARN
+in fix mode, INFO in check mode.
+
+Gate: `make test` must pass. Add a test that simulates a behind-remote repo
+(mock `rev-parse` output).
+
+---
+
+### T03 — DB→file status writeback
+
+```task
+id: CUST-WP-0026-T03
+status: todo
+priority: medium
+state_hub_task_id: "749130f9-b397-46fd-8eb3-43c0fc127dac"
+```
+
+Extend `consistency_check.py --fix` to write DB status back into workplan
+files when DB is ahead of the file (the C-13 case from T01).
+
+**Writeback logic:**
+1. Locate the task block in the workplan file by matching `id: <task_id>`
+2. Replace the `status: <old>` line within that block with `status: <new>`
+3. Stage the file: `git -C <repo_path> add <workplan_file>`
+4. Commit with message:
+   ```
+   chore(consistency): sync task status from DB [auto]
+
+   Updated by fix-consistency on <ISO-date>:
+   - <task_id>: <old_status> → <new_status>
+   ```
+
+**Guard rails:**
+- Only modify lines inside a ` ```task ... ``` ` block
+- Only change the `status:` field — never touch `id:`, `priority:`,
+  `state_hub_task_id:`, or any other field
+- If the workplan file has uncommitted local changes, skip writeback for that
+  file and emit C-14 WARN ("workplan has uncommitted changes — skipping
+  writeback")
+- If git commit fails for any reason, log the error but do not abort the rest
+  of the consistency run
+
+**New flag:** `--no-writeback` — disables T03 behaviour while keeping T01/T02
+active. Default: writeback enabled when `--fix` is set.
+
+Gate: `make test` must pass. The existing workplan parsing tests should cover
+the task block regex; add a writeback-specific test.
+
+---
+
+### T04 — Session protocol update
+
+```task
+id: CUST-WP-0026-T04
+status: todo
+priority: medium
+state_hub_task_id: "59a5d09a-1e67-4749-9d84-039982edc3ef"
+```
+
+Update `the-custodian/CLAUDE.md` session close protocol (step 5) to reflect
+the new behaviour and add the recommended pre-fix step:
+
+**Current step 5:**
+> If any workplan files were written or modified this session, run:
+> `make fix-consistency REPO=the-custodian`
+
+**Updated step 5:**
+> Before running fix-consistency on any repo that has a remote, ensure the
+> local copy is up to date:
+> ```bash
+> git -C <repo_path> pull --ff-only
+> cd state-hub && make fix-consistency REPO=<slug>
+> ```
+> The consistency checker will now warn (C-14) if the repo is still behind
+> and refuse to regress status (C-13). A C-13 warning is normal for repos
+> where work has progressed on a remote machine — it means writeback is
+> keeping the files in sync.
+
+Also update the `state-hub/scripts/project_rules/session-protocol.template`
+so newly registered repos get the updated guidance.
+
+---
+
+### T05 — Makefile: fix-consistency-remote target
+
+```task
+id: CUST-WP-0026-T05
+status: todo
+priority: low
+state_hub_task_id: "b8375cbc-9c44-48f6-a78c-b7333d409525"
+```
+
+Add a convenience target to `state-hub/Makefile` that pulls before fixing:
+
+```makefile
+## Pull repo then sync consistency: make fix-consistency-remote REPO=net-kingdom
+fix-consistency-remote:
+	@test -n "$(REPO)" || (echo "ERROR: REPO is required."; exit 1)
+	$(eval REPO_PATH := $(shell \
+	  curl -s $(API_BASE)/repos/?slug=$(REPO) | \
+	  python3 -c "import json,sys; \
+	    repos=json.load(sys.stdin); \
+	    print(next((r['local_path'] for r in repos if r['slug']=='$(REPO)'), ''))" \
+	))
+	@test -n "$(REPO_PATH)" || (echo "ERROR: repo '$(REPO)' not found in state-hub"; exit 1)
+	git -C "$(REPO_PATH)" pull --ff-only || \
+	  (echo "WARN: pull failed (conflicts or no remote) — running fix-consistency anyway"; true)
+	$(MAKE) fix-consistency REPO=$(REPO) REPO_PATH=$(REPO_PATH)
+```
+
+This makes the safe path the convenient path:
+`make fix-consistency-remote REPO=net-kingdom`
+
+## Done Criteria
+
+- [ ] `make fix-consistency REPO=net-kingdom` never regresses a `done` task
+  back to `todo` when local file is stale
+- [ ] C-13 warning is emitted (not error) when DB is ahead of file
+- [ ] C-14 warning is emitted in fix mode when repo is behind remote;
+  fix operations are skipped for that repo
+- [ ] DB→file writeback commits corrected status to the workplan file
+- [ ] `--no-writeback` flag disables writeback cleanly
+- [ ] `make fix-consistency-remote REPO=<slug>` pulls then fixes in one step
+- [ ] `make test` passes after all changes
+- [ ] Session protocol updated in CLAUDE.md and session-protocol.template
