Deprecated API version warnings logged on every request — log spam

[hman38705]

Labels: observability, api, reliability

Priority: Low

Description

src/versioning.rs logs a WARN message on every request that uses a deprecated API version. High-traffic deployments will flood logs with deprecation warnings, obscuring real errors and increasing logging costs.

Acceptance Criteria

• Change deprecation warnings to use per-client sampling (e.g., log at most once per client IP per hour)
• Track a Prometheus counter deprecated_api_calls_total{version} instead of per-request logs
• Add a Grafana panel for this counter to the monitoring dashboard
