fix: defaut ui triage (#4802)

* 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
