- Remove the unused "Enable Connect" setting and its strings
- Redesign RemoteControlScreen to match the expanded player: artwork sized
to fit, side-by-side queue panel on wide screens, proper connecting /
disconnected / error states, "Playing on <device>" subtitle
- Seek and volume sliders keep local drag state and only commit on release
(volume throttled while dragging) instead of sending a command per frame
- Redesign DevicesScreen with the settings card components, a connected
device card, error banner and empty state; ViewModels expose one UiState
- Fix tapping an already-connected device doing nothing; reopen its remote
screen instead, and switch devices by disconnecting first
- Fix the controller getting stuck in Connecting after the host denies a
request: Ktor never delivers Close frames to `incoming`, so detect the
close reason after the receive loop ends
- Fix a UI freeze when leaving the devices screen on desktop: run discovery
(and JmDNS's blocking close/resolve) on Dispatchers.IO
- Advertise the LAN address of the default-route interface on desktop;
dns-sd-kt otherwise picks any site-local address, e.g. a Docker bridge
