- Fix ElGamalEncryption to generate keypair on initialization and provide public_key_bytes property with proper "p:g:h" UTF-8 format
- Add ElGamal alias for backward compatibility with imports
- Improve frontend error handling with detailed base64 decode error messages
- Update .gitignore to specifically ignore backend/lib/ and backend/lib64/ instead of all lib directories, preserving frontend node_modules-style lib/
This fixes the "Invalid public key format" error that was preventing vote submission during testing.
