Tolerate space-padded pactl output, and show the running app version

Browse Source 
The device-source parser assumed pactl list short sources is strictly
tab-separated, true for stock PulseAudio but not guaranteed for a
TV's own heavily customized audio stack (this one names sources
tpcm_output/tpmedia/tptts/... — clearly not vanilla). A different
separator would have silently produced zero parsed sources with no
error, and the picker's own `when` guard would then just hide the row
entirely rather than show anything broken. Split on any whitespace
run instead of a literal tab; source names never contain embedded
whitespace, so this is strictly more permissive with no new failure
mode. Confirmed end to end on real hardware: tptts.monitor lit up
during the accessibility voice guide and reached HyperHDR.

Also: the System panel now shows the app's actual running version,
read from a <meta> tag substituted at package time (tools/build.sh
stage()) from frontend/appinfo.json — not hand-maintained, so it can't
drift from what was actually built. Requested after a version bump
alone wasn't enough to tell whether a reinstall had truly picked up
new files versus served something cached along the way; this settles
that question by inspection instead of by inference. Bumped to 1.0.2.
