feat(15-03): add Grafana and Sentry ReconSource implementations

- GrafanaSource: search dashboards via /api/search, fetch detail via /api/dashboards/uid
- SentrySource: search issues via /api/0/issues, fetch events for key detection
- Register all 5 log aggregator sources in RegisterAll (67 sources total)
- Tests use httptest mocks for each API endpoint
