Add missing blank line between the _set_timestamp_defaults helper
and the next top-level constant so `ruff format --check .` passes.
Pre-existing on dev's HEAD; surfaced after rebasing PR #39 onto dev
in 2b20946.

QA review of PR #39 (CAR-1121) identified three blocking issues; this
commit addresses all three plus the typecheck errors flagged as CI RED.
CAR-1077 (PR #39) changes:
- database.py: add pool_timeout=30 so the engine fails fast when the
connection pool is exhausted (defends against the "server closed
connection unexpectedly" pod failures).
- routes/health.py: /health now calls SELECT 1 through Depends(get_db)
and raises HTTPException(503) when the database is unreachable, so
Kubernetes readiness probes can correctly mark the pod unhealthy and
stop routing traffic to it. Logs the failure at exception level for
observability.
- Drop .mcp.json from this PR (root-level MCP server config, not
related to the pool fix; tracked separately).
CI typecheck fixes (pre-existing on dev, were failing mypy on PR #39):
- auth/passwords.py: cast bcrypt return values so mypy doesn't widen
to Any.
- config.py: silence the false-positive call-arg on Settings() — the
three required fields are populated from the environment by
pydantic-settings at runtime.
- cache.py: coerce the bytes/str union returned by the redis client
to the documented str | None return type.
- middleware/rate_limit.py: annotate the three module-level limiters
with the RateLimitBackend protocol, cast the redis zrange score to
float before arithmetic, and add max_requests/window_seconds to the
protocol so the response-header builder can read them.
