native: group and channel volume settings from the chat options sheet

[latter-bolden]

Moved db volume setting types over to their true values vs a native app simplified isMuted/isNoisy. Handles scry and sub updates to base. Adds a basic UI for setting group volume level which checks recursively against base (needs polish).

Still todo:

• robust handling of recursive volume reads wherever they're accessed
• ensure however these settings gel with top level Push Notification is baseline acceptable
  • we might be able to punt on Exceptions in the settings menu, but that probably needs to start coming into play
  • we need to think through the UX of communicating what exactly this setting does

From Pat: updated to work with the new Chat Options Sheet, also made it work for channels from that sheet. Not clear on whether we still need the other todos before merging.
