Fix TypeScript errors blocking Docker build

- Fix Authentik button type casting issue in login page
  * Use exported signIn instead of authClient type assertion
  * Add proper error handling for OAuth calls

- Fix image MIME type handling in import-photo.ts
  * Convert base64 to data URL format for AI SDK compatibility

- Fix type annotations in auth/server.ts changeEmail handler
  * Add explicit type annotation for destructured parameters

These TypeScript errors were preventing 'pnpm build' from completing
during Docker image build process.
