feat(sec-lint): lint+backfill system for SEC data gaps (B1-B4)

- SecLintAdapter implements SourceFetch, runs via shared queue/drain loop
- Two new SourceKinds: sec-lint-holders, sec-lint-insiders (weekly schedules)
- No-op cache handlers so drain->cache.set doesn't throw on lint keys
- tRPC admin.queueLint(symbol, kind) — run lint for one symbol, returns LintResult
- tRPC admin.queueLintAll(kind) — backfill ALL watched symbols at once
- tRPC admin.dataQualityList() — query data_quality rows (filterable by symbol/kind)
- InstitutionalDashboard: 'Lint holders' button + status badge in detail panel header
- Admin queue page: Data Quality section with per-row status badges, 'Lint all' buttons
- DEFAULT_RATE_MS includes 167ms (~6 req/s) for lint kinds matching EDGAR limiter
