fix(login): Improve Passkey Authentication Error Handling & Testing (#10971)

# Which Problems Are Solved

This PR enhances the passkey authentication flow with comprehensive
error handling, full internationalization support, and extensive test
coverage.

# How the Problems Are Solved

I18n:
- Replaced all hard-coded error messages with i18n translation keys
- Consistent error messaging throughout the passkey flow
- Added specific error handling for passkey cancellation
(NotAllowedError)
- Implemented fallback errors for undefined/missing responses
- Better error messages for:
  - Session retrieval failures
  - Challenge request failures
  - User verification errors
  - Redirect determination issues

Tests:
- Added `login-passkey.test.tsx` with 100+ test cases covering:
  - Successful verification flows
  - Error scenarios and edge cases
  - Props handling
  - Component lifecycle
- Added passkeys.test.ts with server-side function tests:
  - Session cookie retrieval
  - User validation
  - Custom lifetime handling
  - Critical fallback error paths
  
Try-catch blocks around critical user retrieval operations
Defensive checks for undefined responses from completeFlowOrGetUrl
Support for custom lifetime parameters
Cleaner error propagation
