89d826be2 raised backend/go.mod to `go 1.26.6` and updated the three CI
workflows' version assertions, but left the Go builder image in all three
Dockerfiles pinned at 1.26.5. Since the official golang images set
GOTOOLCHAIN=local, the toolchain is not auto-downloaded and any image build
fails hard at `go mod download`.
CI does not catch this: the workflows build with actions/setup-go, not with
these Dockerfiles.
Also extend the Go-upgrade checklist in DEV_GUIDE.md, which listed only the
CI files -- that omission is why the Dockerfiles were missed.
This feature allows API Keys to have their own quota limits and expiration
times, independent of the user's balance.
Backend:
- Add quota, quota_used, expires_at fields to api_key schema
- Implement IsExpired() and IsQuotaExhausted() checks in middleware
- Add ResetQuota and ClearExpiration API endpoints
- Integrate quota billing in gateway handlers (OpenAI, Anthropic, Gemini)
- Include quota/expiration fields in auth cache for performance
- Expiration check returns 403, quota exhausted returns 429
Frontend:
- Add quota and expiration inputs to key create/edit dialog
- Add quick-select buttons for expiration (+7, +30, +90 days)
- Add reset quota confirmation dialog
- Add expires_at column to keys list
- Add i18n translations for new features (en/zh)
Migration:
- Add 045_add_api_key_quota.sql for new columns
