Add user-configurable colors for transcription display

- Add color settings (user_color, text_color, background_color) to config
- Add color picker buttons in Settings dialog with alpha support for backgrounds
- Update local web display to use configurable colors
- Send per-user colors with transcriptions to multi-user server
- Update Node.js server to apply per-user colors on display page
- Improve server landing page: replace tech details with display options reference
- Bump version to 1.3.2
