fix(privacy): detect screen casting on Niri via PipeWire (#2185)

Browse Source 
Screen sharing was not detected by PrivacyService on Niri because:

1. Niri creates the screencast as a Stream/Output/Video node, but
   screensharingActive only checked PwNodeType.VideoSource nodes.

2. looksLikeScreencast() only inspected application.name and
   node.name, missing Niri's node which has an empty application.name
   but identifies itself via media.name (niri-screen-cast-src).

Add Stream/Output/Video to the checked media classes and include
media.name in the screencast heuristic. Also add a forward-compatible
check for NiriService.hasActiveCast for when Niri gains cast tracking
in its IPC.
