fix(WP-0017/E4): Layer 3 error fixes — round 2 (18 files)

Fixes 46 compile errors across 18 controllers and views:
- BridgeResponse missing from explicit import lists (Widgets, RequirementCandidates,
  DecisionRecords, AgentDelegations) — dot-notation HasField resolution fails without
  the type in scope under DuplicateRecordFields
- unId not in IHP v1.5 — replaced all fmap (Id . unId) with fmap coerce
- respondWith not in IHP — replaced with plain redirectTo in 5 controllers
- [hubId] list param to sqlQuery — replaced with (Only hubId) tuple
- deleteWhere not in IHP — replaced with query/filterWhere/fetch/deleteRecords
- fill @'["label"] mismatch — field is label_ in generated types, not label
- PersistUUID/toUUID (persistent-style) — replaced with (Only id)
- intercalate + jsonArrayTexts ambiguity in GovernanceTemplates — hid Index import,
  removed local duplicates, added Data.Text (intercalate)
- Int16 not in scope in AntifragilityDashboard — changed to Int (score :: Int)
- typeArraySection type mismatch in HubCapabilityManifests/Edit — unified to [Text]
- renderForm arity mismatch — added action param to DecisionRecords/New.renderForm
- Missing qualified Data.Aeson import in AdaptiveThresholds
- Missing ?request::Request constraint in Api/V2/WidgetPatterns.renderJsonWithStatus
