feat(warden): implement WARDEN-WP-0002 correctness and operational completeness

Browse Source 
T1 — TTL max enforcement:
  - models.py: MAX_TTL_HOURS policy constant
  - ca.py: _enforce_ttl() raises CAError when spec.ttl_hours > type max
  - Called at top of LocalCA.sign() and VaultCA.sign()
  - scorecard.py: check_ttl_policy() — flags certs with issued TTL > type max
  - run_scorecard() now returns 5 checks

T2 — Stale cert cleanup:
  - ca.py: _evict_cert() removes existing cert before writing new one (no accumulation)
  - cli.py: warden cleanup [actor] [--dry-run] command
  - check_no_stale_certs detail suggests 'warden cleanup' when stale certs found

T3 — Outgoing signatures log:
  - ca.py: _append_signature_log() writes JSONL to state_dir/signatures.log
  - Called after every successful sign() in LocalCA and VaultCA
  - cli.py: warden log [actor] [--last N] [--json] command
  - parse_cert_metadata now also returns valid_from (needed for TTL policy check)

61 tests passing, ruff clean.

## Acceptance Criteria
- [ ] `warden sign agt-test --pubkey /tmp/k.pub --ttl 100` raises `CAError`
- [x] `warden sign agt-test --pubkey /tmp/k.pub --ttl 100` raises `CAError`
(agt max is 24h)
- [ ] `warden sign agt-test --pubkey /tmp/k.pub --ttl 24` succeeds
- [ ] `warden scorecard` includes TTL policy check; fails when a cert exceeds type max
- [ ] After `warden sign`, `state_dir/signatures.log` has one new line; valid JSON
- [ ] `warden log` renders a table; `warden log --json` is parseable
- [ ] `warden log --actor agt-test` returns only entries for that actor
- [ ] `warden cleanup --dry-run` lists stale certs without deleting
- [ ] `warden cleanup` removes stale certs; scorecard `no_stale_certs` passes after
- [ ] Re-signing an actor replaces its cert file (no accumulation)
- [ ] All tests pass: `uv run pytest`
- [ ] All lints pass: `uv run ruff check .`
