wasm: fix uncaught AbortError from video.play() in camera output

mediaVideoStreamReady can fire again for an already-active stream, which
re-set srcObject and interrupted the in-flight play(). Its unhandled
promise then surfaced as an uncaught AbortError in the console.

Skip re-assigning srcObject when unchanged, and route play() through a
helper that swallows the benign rejection.

Pick-to: 6.12

wasm: stabilize media device enumeration order and defaults

The camera and audio device lists were stored in QMaps keyed by the
browser's opaque deviceId, so QMediaDevices returned them sorted by a
random hash. Hot-plugging a device could reorder the lists, silently
switching index-based consumers (e.g. a ComboBox bound to videoInputs)
to the new device. Store them in insertion-ordered QLists instead.

The default was whichever device was enumerated first. Chrome and Edge
enumerate a synthetic "default" entry ahead of the real devices, so the
flag landed on an alias rather than on the device it points at, and
never moved once the system default changed. Resolve that entry back to
the real device through the groupId they share, and drop it from the
lists along with "communications", where both appeared as duplicates.

Firefox and Safari have no such entry and enumerate the default first,
so first-in-wins remains the fallback, cameras have no default entry in
any browser and always take that path. The flag is recomputed on every
enumeration, so it also follows hot-plug and system default changes.
