Felipe Cardoso d0b717a128 Enhance demo mode credential validation and refine MSW configuration
- Updated demo credential logic to accept any password ≥8 characters for improved UX.
- Improved MSW configuration to ignore non-API requests and warn only for unhandled API calls.
- Adjusted `DemoModeBanner` to reflect updated password requirements for demo credentials.
