feat(service): add /healthz endpoint for dependency health checks (#925)

* feat(service): add /healthz endpoint for dependency health checks

Expose a health check endpoint that reports database and graph-node connectivity status,
enabling load balancers and orchestration tools to detect service degradation.

Closes #503

* refactor(test-assets): share PostgreSQL container across tests

Reuse a single PostgreSQL container for all test databases instead of
starting a new container per test. Reduces test execution time and
resource usage when running multiple integration tests.

* fix(service): prevent /healthz from hanging on slow graph-node responses

Add 5-second timeout to graph-node health check to ensure load balancers
receive timely responses even when graph-node is degraded. Standardize
status response to "healthy"/"unhealthy" for consistency.

* test(service): verify /healthz returns 503 when graph-node is unavailable

Add test coverage for the unhealthy dependency scenario to ensure the
health endpoint correctly reports service degradation to load balancers.

* fix(service): add database timeout and standardize /healthz status labels

Add 5-second timeout for database health checks to prevent /healthz from
hanging when the database is slow or unresponsive. Standardize all health
check status labels to "healthy"/"unhealthy" for consistent responses.

* fix(service): use simpler introspection query for graph-node health check

Replace `indexingStatuses` query with `__typename` introspection to check
graph-node connectivity. This works even when no subgraphs are deployed.

* fix(local-network): remove duplicate port mapping and improve shell script robustness

Remove duplicate 7302:7300 port mapping in local-network.patch that would
cause Docker Compose to fail. Also refactor close-allocations.sh to use
array-based command building for safer argument handling, and add
clarifying comments about mnemonic parsing limitations.
