Switch from sessionStorage to localStorage so the auth token survives
across tabs and browser restarts, matching standard platform behavior.
Also guard the signup redirect in App.tsx behind profileLoaded to avoid
a false redirect when the instance profile fetch fails.
When no token exists in sessionStorage, AuthContext.initialize() was
still calling GetCurrentUser, triggering the auth interceptor to attempt
RefreshToken and retry — producing a burst of 5+ auth API calls in under
a second that reverse proxies with rate limiting (e.g. CrowdSec) flag as
brute force.
Add hasStoredToken() to auth-state and bail out of initialize() early
when there is definitively no session to restore. The refresh flow for
expired tokens is preserved since hasStoredToken() checks for presence
regardless of expiry.
Fixes#5647
Optimizes React Query migration with performance and consistency improvements:
Performance:
- Memoize AuthContext and InstanceContext provider values to prevent unnecessary re-renders
- Convert InstanceContext getter functions to useMemo hooks
- Fix refetchSettings to avoid state dependency that caused frequent recreations
Type Safety:
- Replace 'any' types in useAttachmentQueries with proper protobuf types
- Add Attachment and ListAttachmentsRequest type imports
Query Key Consistency:
- Replace hardcoded ["users", "stats"] with userKeys.stats() factory function
- Ensures consistent cache key management across mutations
Developer Experience:
- Rename unused useCurrentUser to useCurrentUserQuery to avoid confusion
- Add documentation explaining AuthContext-based vs React Query current user hooks
- Update internal references in useNotifications and useTagCounts
All changes verified with TypeScript compilation and build tests.
