fix(ios): declare background audio so calls survive minimising the app

Browse Source 
Capacitor/WebView apps get suspended by iOS a few seconds after backgrounding, which
freezes the WebRTC mic + audio pipeline — so when the user minimised the app or locked
the phone during a call, no one could hear anyone. Add UIBackgroundModes=[audio] to
Info.plist (via ios-patch.sh) so iOS keeps the audio session (and the app) alive while
a call is actively playing/recording. Video rendering still pauses in the background
(unavoidable in a WebView) but voice continues. Needs a fresh Codemagic build.

# ── Keep CALL AUDIO alive when the app is BACKGROUNDED (minimised / screen locked) ──────────────────
# Without the 'audio' background mode, iOS suspends the WebView a few seconds after it backgrounds, which
# freezes the WebRTC mic + audio pipeline — so participants can't hear each other once the app is minimised
# or the phone locks. Declaring background audio keeps the audio session (and the app) running so a voice
# call continues in the background. (Video RENDERING still pauses while backgrounded — unavoidable in a
# WebView — but audio keeps flowing, which is what matters for a call.) Idempotent: rebuild the array each run.

# ── Custom URL scheme so the Share Extension can bounce the user back into the app ──────────────────
# The extension stages the shared files into the App Group, then opens bizconnect://share; the app reads
# the staged files and shows "Send to…". Registering the scheme is what makes that openURL succeed.
