Currently only 2 options are implemented, mainly aimed at helping troubleshoot
audio related problems:

- Disable native call integration (it disables CallKit / ConnectionService)
- Disable P2P

* Adds notifications for who stop/start recording/live streaming.

* Updates to latest lib-jitsi-meet.

Fixes: #312

This commit refactors device selection (more heavily on iOS) to make it
consistent across platforms.

Due to its complexity I couldn't break out each step into separate commits,
apologies to the reviewer.

Changes made to device handling:

- speaker is always the default, regardless of the mode
- "Phone" shows as a selectable option, even in video call mode
- "Phone" is not displayed when wired headphones are present
- Shared device picker between iOS and Android
- Runtime device updates while the picker is open

It's an evolution of audio-only mode, where we also allow for receiving a remote
screen-share.

Diving deeper: this basically sets last N to 1 or 0 depending on the
availability of a screen-share.

This prevents inserting any user overridden APP_NAME
values into html. A new translation key is being used
to immediately stop non-english languages from using the
problematic string.

Also tweaked the copy to remove the "eer" and fix
some grammar.

i18next.options are initialized before interfaceConfig overwrites are processed which leads to wrong translations.
