Allow admin panel updates to be saved while overrides remain effective; remove WG_ENABLED

- Remove WG_ENABLED environment variable (interface cannot be disabled)
- Allow all admin panel updates to be saved to database
- Environment variable overrides take precedence at runtime only
- Users can now update values in admin panel even when overridden
- Updated documentation to clarify override behavior
