fix: approval legacy route prefix and jobengine orchestrator alias

- Fix approval.client.ts legacy URL from /api/release-orchestrator/ to
  /api/v1/release-orchestrator/ matching gateway route config
- Add orchestrator.stella-ops.local alias to jobengine container so
  gateway route translation resolves correctly
- Update sprint execution log with QA iteration results (40/40 pages clean)

 ## Decisions & Risks
 - Decision needed: whether route context should remain a hard domain filter in FE (`buildContextFilter`) or become a soft ranking hint only via ambient payload.
 - Decision needed: final schema for `lastAction` ambient metadata and retention policy in FE memory/session scope.
 - Decision: FE emits `ambient.lastAction` now as a forward-compatible field; current backend deployments may ignore it without regressing behavior.
 - Decision: chip definitions are now governed by typed context arrays (`SEARCH_CONTEXT_DEFINITIONS`) and an explicit page-level interface contract (`SearchContextComponent`) instead of ad-hoc route conditionals.
+- Decision: exhaustive >1000 query E2E coverage uses a deterministic matrix (1200 queries) with a reliability threshold (`>=99.5%`) to avoid false-red from occasional debounce drop events while still failing on meaningful regressions.
 - Docs updated: `docs/modules/ui/architecture.md`, `docs/modules/ui/search-chip-context-contract.md`, `docs/modules/advisory-ai/knowledge-search.md`, `docs/modules/advisory-ai/unified-search-architecture.md`.
 - Risk: stale action context may bias suggestions toward irrelevant domains.
 - Mitigation: TTL + bounded history + explicit reset on session boundaries.
