- 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
ValidateAndFill now checks the DB query result and returns sentinel errors
(ErrDatabase, ErrInvalidCredentials, ErrUserEmptyCredentials) instead of
hardcoded Chinese strings. The controller maps each sentinel to the
appropriate i18n message, so users see "please contact admin" on DB errors
instead of a misleading "wrong password" message. Non-DB errors still
return a unified vague response to avoid leaking user existence.
- 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.
