Add frontend UI for configuration management

Issue Description

Currently, users need to edit Python files (local.py) to configure the application. This is not user-friendly and requires technical knowledge. We need a frontend UI that allows users to manage their configuration without editing files directly.

Proposed Features

1. Configuration Management UI:

   • View current configuration
   • Add/remove/edit stops
   • Add/remove/edit monitored lines
   • Set map preferences
   • Save/load configurations

2. Interactive Stop Selection:

   • Map-based stop selection
   • Search stops by name/ID
   • Preview stop information before adding

3. Configuration Storage:

   • Store configurations in a database or JSON file
   • Export/import configurations
   • Configuration versioning
   • Backup/restore functionality

Technical Considerations

1. Backend Changes:

   • API endpoints for configuration management
   • Configuration validation
   • Secure storage of sensitive data
   • Hot reload of configuration changes

2. Frontend Implementation:

   • User-friendly forms
   • Real-time validation
   • Interactive map integration
   • Responsive design

3. Security:

   • Authentication for configuration changes
   • Validation of user input
   • Protection against malicious configurations

Success Criteria

• Users can manage all configurations without editing files
• Changes are applied without server restart
• Configuration changes are validated and stored securely
• User-friendly interface with clear feedback
