feat: implement password reset for shop customers

Add complete password reset functionality:

Database:
- Add password_reset_tokens migration with token hash, expiry, used_at
- Create PasswordResetToken model with secure token hashing (SHA256)
- One active token per customer (old tokens invalidated on new request)
- 1-hour token expiry for security

API:
- Implement forgot_password endpoint with email lookup
- Implement reset_password endpoint with token validation
- No email enumeration (same response for all requests)
- Password minimum 8 characters validation

Frontend:
- Add reset-password.html template with Alpine.js
- Support for invalid/expired token states
- Success state with login redirect
- Dark mode support

Email:
- Add password_reset email templates (en, fr, de, lb)
- Uses existing EmailService with template rendering

Testing:
- Add comprehensive pytest tests (19 tests)
- Test token creation, validation, expiry, reuse prevention
- Test endpoint success and error cases

Removes critical launch blocker for password reset functionality.
