Refactor process picker into palette pattern, add notification app picker

- Refactor process-picker.ts into generic NamePalette with two concrete
  instances: ProcessPalette (running processes) and NotificationAppPalette
  (OS notification history apps)
- Notification color strip app colors and filter list now use
  NotificationAppPalette (shows display names like "Telegram" instead of
  process names like "telegram.exe")
- Fix case-insensitive matching for app_colors and app_filter_list in
  notification_stream.py
- Compact browse/remove buttons in notification app color rows with
  proper search icon
- Remove old inline process-picker HTML/CSS (replaced by palette overlay)
