Health checks (/health, /ready)

[unrealbg]

Problem

No health endpoints for liveness and readiness, making monitoring and orchestration harder.

Proposal

• Add /health for liveness (always returns OK)
• Add /ready for readiness (checks DB connectivity and disk space)
• Tag and log responses

Alternatives considered

• Health checks only via external tools.

Acceptance criteria

• /health returns OK regardless of DB state
• /ready checks DB connectivity and disk space
• Responses tagged and logged

Technical notes

• Microsoft.Extensions.Diagnostics.HealthChecks
• Map endpoints and add Serilog logging

Risks

• Health endpoints may be abused for info leaks if not secured/logged.
