fix: resolve branding display issues and invitation parsing errors

Fixes #84 - Logo and favicon not displaying on branding page and galleries
Fixes #85 - Invitations showing undefined expiresAt causing parseISO errors

Changes:

- Fix vite.config.ts: Add /uploads proxy for development environment
- Fix BrandingPage.tsx: Include logo_url from branding settings instead of expecting it from theme
- Fix adminUsers.js: Add transformInvitation() to convert snake_case DB fields to camelCase API response
- Fix publicSettings.js: Add branding_hide_powered_by to public settings API response
- Update README.md: Mark Multiple Administrators feature as implemented
- Bump version to 2.2.1
