gsxdsm 8dd9697468 FN-6714: backfill commit-association diff stats

Backfill historical commit-association diff stats so Command Center LOC can use real persisted git data.

- Add a core backfill API that inspects local git commits for associations with missing additions/deletions and supports dry-run reporting.
- Expose an authenticated Command Center productivity backfill endpoint and route it through the legacy API shim.
- Keep productivity LOC/hour sentinels safe for legacy payloads and document the backfill contract.
- Cover the backfill path, auth gate, productivity analytics, and route registration with tests.
