- Create model/errors.go to centralize all sentinel errors
- ValidateAccessToken now returns error to distinguish DB failures
- ValidateUserToken uses unified ErrTokenInvalid for all auth failures
(expired/exhausted/disabled/not-found) to prevent token enumeration
- authHelper and TokenAuthReadOnly use i18n messages instead of
hardcoded Chinese strings
- All err.Error() removed from user-facing responses; DB errors logged
server-side and return generic "contact admin" message (HTTP 500)
- Migrate ErrRedeemFailed, ErrTwoFANotEnabled to model/errors.go
- Refactor token, redemption, and user quota inputs to prioritize monetary
amount entry, with raw quota input collapsed by default
- Add atomic quota adjustment modal for users with add/subtract/override modes,
bypassing batch update queue for immediate DB consistency
- Make user quota fields readonly in edit form; all modifications go through
the dedicated adjust-quota modal via POST /api/user/manage
- Add DecreaseUserQuota `db` parameter for direct DB writes, matching
IncreaseUserQuota behavior
- Support negative quota display in amount conversion helpers
- Add i18n keys for all new UI strings across all locales
Add new endpoint POST /api/token/batch/keys to fetch multiple
token keys in a single request, improving performance when
exporting or copying multiple tokens.
