fix: Switch to base64 photo upload for compatibility

The MinIO/Sharp approach doesn't work on the current server CPU architecture.
Switched to simple base64 encoding for photo uploads.

Changes:
- PhotoUpload component converts images to base64 data URLs
- 5MB file size limit
- Works on all platforms without external dependencies
- Stores photos directly in database (photoUrl field)

This is a temporary solution. For production scalability, we can:
- Upgrade server CPU to support Sharp
- Build Sharp from source
- Use Docker with prebuilt Sharp binaries
- Migrate to a proper CDN/object storage later
