fix: replace bits-ui Select with native HTML select

- Remove bits-ui Select component dependency
- Use native HTML select element for device selection
- Simplify state management (single mappings Map)
- Fix selection handling with direct onchange event
- Add visual indicator for exact name matches
- Resolves selection not working issue
