Adds a fifth mixer tab, Cards: one row per pactl card (onboard audio, USB
headsets, HDMI, Bluetooth) with just its profile dropdown (Analog Stereo
Duplex, Pro Audio, Off, etc.).
Profile is a card-level setting, not a per-device one — a single card can
back a device in both Output and Input Devices at once, and switching its
profile can make either side appear or disappear entirely. It used to live
on individual DeviceCards in both tabs, which was confusing (same card,
edited from two places) and is exactly what pavucontrol avoids by giving
profiles their own "Configuration" tab. Pulled it out of DeviceCard/
OutputTab/InputTab (which also drops their now-unneeded list_cards() fetch)
and into a new ui/profile_card.py + ui/cards_tab.py.
hyprlua's audio-panel picks this up via regen-audio-panel.sh, unchanged.
