🐛 fix: sidebar scroll on mobile dynamic viewport

✨ fix: Improve subscription payment handling and card layout consistency

Use dynamic viewport height to prevent sidebar scroll lock in mobile browsers
Harden sidebar scroll container with min-height and momentum scrolling

Unify Epay subscription response format with top-up flow, and harden frontend error handling to avoid object-to-string issues. Refine subscription plan cards layout to be wider, left-aligned, and visually consistent across breakpoints.

The i18n middleware runs before UserAuth, so user settings weren't
available when language was detected. Now GetLangFromContext checks
user settings first (set by UserAuth) before falling back to the
language set by middleware or Accept-Language header.

- Change default language fallback to English instead of Chinese
- Add ErrRedeemFailed typed error for model layer translation
- Migrate remaining hardcoded messages in controller/user.go
- Add translation keys: redeem.failed, user.create_default_token_error, common.uuid_duplicate, common.invalid_input

fix: default summary = detailed
