Add password reset mechanism (Issue #1)
- Added reset_token and reset_token_expiry fields to User model - Implemented generate_reset_token(), verify_reset_token(), and clear_reset_token() methods - Created password reset request form (/password-reset-request) - Created password reset form (/password-reset/<token>) - Added "Forgot password?" link to login page - Reset tokens expire after 1 hour for security - Created migration script to add new database columns - Reset links are logged (would be emailed in production) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
