- Use getMimeType() instead of getClientMimeType() to prevent MIME spoofing
- Change IsGranted to IS_AUTHENTICATED_FULLY so ROLE_CLIENT can access avatars
- Remove Groups from avatarFileName (only avatarUrl needed by frontend)
- Disable aggressive caching to prevent stale avatar images
- Add error handling to avatar upload in profile page
- Use i18n for "Mon profil" button text

Wrap title + filters in a sticky container (top-8 sm:top-12, z-20, bg-white)
on all pages for consistent scroll behavior. Also fix SidebarTimer icon
visibility when sidebar is collapsed.
