A community based topic aggregation platform built on atproto

fix(auth): prevent goroutine leak from DPoP replay cache

The DPoP verifier starts a background goroutine for nonce cache cleanup.
Without calling Stop(), this goroutine persists and accumulates across
server reloads and test runs.

Changes:
- cmd/server/main.go: Add graceful shutdown with signal handling
- Listen for SIGINT/SIGTERM
- Call authMiddleware.Stop() during shutdown
- Use http.Server.Shutdown() for graceful connection draining

- Integration tests: Add defer authMiddleware.Stop() after creation
- user_journey_e2e_test.go
- post_e2e_test.go
- community_e2e_test.go
- aggregator_e2e_test.go
- jwt_verification_test.go (2 locations)

This prevents NonceCache cleanup goroutines from leaking in both
production and test environments.
