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.
Introduce `CalculateTrendFloatWithBaseline` to correctly handle scenarios where previous period metrics (Error Rate, Latency) are zero or missing. This prevents arithmetic errors and distinguishes between "new" data and actual increases ("up") when starting from zero.
Also updates the admin panel dashboard documentation to reflect current project status.
Remove the DailyStatsJob, DailyStat model, and associated database
migrations. This eliminates the pre-aggregation layer and updates the
dashboard handler to remove dependencies on the daily_stats table.
- Add `include_trends` query parameter to enable trend calculation
- Implement trend comparison logic (delta % and direction) against previous periods
- Add support for `last7d`, `last30d`, and `all` time period options
- Update `DashboardSummaryResponse` to include optional `trends` field
- Add helper functions for custom time window aggregation
- Add unit tests for trend calculation and period window logic
- Update feature documentation with new parameters and response schemas
Add new admin API endpoints for dashboard metrics and system-wide
realtime statistics:
- Add /admin/dashboard/summary endpoint with aggregated metrics
including requests, tokens, latency, masters, keys, and provider
keys statistics with time period filtering
- Add /admin/realtime endpoint for system-level realtime stats
aggregated across all masters
- Add status filter parameter to ListAPIKeys endpoint
- Add hour grouping option to log stats aggregation
- Update OpenAPI documentation with new endpoints and schemas
