Full mixer implementation — tray, popup, prefs, devices tab with port indicators

Adds the complete tmix feature set built since the initial skeleton:
balance knob, level meters, KLed mute button, system tray with scroll-wheel
volume and recording indicator, tray popup, preferences dialog, right-click
context menus, single-instance enforcement, scroll area, window geometry
persistence, and Devices tab with PA card profile switcher and live port
availability indicators (2-column layout, in-place updates on plug/unplug).
