fix(FN-2545): persist memory audit extraction state and polish MemoryView

- Persist extract-to-audit continuity state in memory insights so extraction progress survives follow-up runs
- Add core and dashboard route tests that cover audit extraction flow and prevent regressions
- Restore lint/typecheck baseline by removing obsolete planning subtask route wiring from dashboard routes
- Apply MemoryView UX refinements with updated component logic and dedicated styling adjustments
