Add admin endpoints to list and revoke child keys under a master.
Standardize OpenAPI responses to use ResponseEnvelope with MapData
for error payloads, and regenerate swagger specs accordingly.
Add response envelope middleware to standardize JSON responses as
`{code,data,message}` with consistent business codes across endpoints.
Update Swagger annotations and tests to reflect the new response shape.
BREAKING CHANGE: API responses are now wrapped in a response envelope; clients must read payloads from `data` and handle `code`/`message` fields.
Add ReportAlerts endpoint for Data Plane to report alerts to Control Plane
with fingerprint-based deduplication using a 5-minute cooldown period.
Changes:
- Add POST /internal/alerts/report endpoint with validation
- Add Fingerprint field to Alert model for deduplication
- Extend GetAPIKeyStatsSummary with optional time range filtering
using since/until query parameters to query from log records
Introduce internal endpoint for flushing accumulated APIKey statistics
from data plane to control plane database, updating both individual
API keys and their parent provider groups with request counts and
success/failure rates.
Add admin endpoint to retrieve aggregated API key statistics summary
across all provider groups, including total requests, success/failure
counts, and calculated rates.
