Voice2Text AI microphone dropdown readability fix

This overlay updates the existing release/v0.4.0-native-linux branch.

Changes:

Widens the Preferences dialog.
Shows the complete selected microphone name as the row subtitle and tooltip.
Uses a wider selected-value label with middle ellipsis only when unavoidable.
Wraps every microphone source name in the dropdown list, so long PipeWire, ALSA, USB, monitor, and hardware source names can be read in full.
Does not alter dictation, rendering, TTS, Flatpak dependencies, or settings.
