Auth & Sync Infrastructure Improvements

[MelbourneDeveloper]

TLDR;

File logging for all APIs, shared JWT signing key for local dev, incremental sync with version tracking, DataProvider methods replacing raw SQL.

Brief Details

• Logging: Added FileLoggerProvider to Gatekeeper, Clinical, and Scheduling APIs
• Auth: Default JWT key now deterministic (32 zeros) so all local APIs validate each other's tokens
• Sync: Tracks last synced version in _sync_state table, requests only new changes via fromVersion param
• TokenService: Swapped inline SQL for generated RevokeSessionAsync/GetSessionRevokedAsync
• Misc: Code formatting, pre-generated UUIDs in SampleDataSeeder, website hero block removed

How Do The Tests Prove This Works?

• Gatekeeper.Api.Tests validates token generation/revocation with new DataProvider methods
• Clinical.Api.Tests confirms API endpoints work with shared JWT validation
• Sync version tracking tested by running sync worker multiple times—only new changes processed
