* fix: purge authentication data on hard user deletion
* fix: fail closed when 2FA status lookup fails
* fix: reject stale Telegram login callbacks
* fix(twofa): prevent concurrent backup code and lockout bypasses
* fix(auth): harden user deletion and Telegram verification
* fix: theme-aware payment paths, auto-group validation, route guards, perf group filtering
- Add common.ThemeAwarePath to generate correct redirect URLs based on
active theme (default vs classic), replacing hardcoded /console/* paths
in 7 controllers and service/quota.go (#4765)
- Validate auto-group availability against getUserGroups before defaulting
form values; playground falls back to 'default' group when 'auto' is
unavailable (#4796, #4799)
- Enforce HeaderNavModules settings in rankings route (frontend + backend
API) and SidebarModulesAdmin in playground route to block direct URL
access when features are disabled (#4704, #4512)
- Filter perf_metrics API response to only include currently configured
groups, hiding stale data from deleted groups (#4790)
- Preserve query params (pay=success/fail) in /console/topup → /wallet
frontend redirect
* fix: update hero section text and localization strings for clarity
