Include Channel Number with Live TV Channel Title

[michaelcresswell]

Is your feature request related to a problem? Please describe

I receive live TV broadcasts for multiple regions and in multiple formats (i.e. the same network in ASTC 1.0 & ASTC 3.0). This means I get multiple broadcasts of ABC, CBS, NBC, etc. A call sign and/or a network logo are not always enough for me to disambiguate channels.

Describe the solution you'd like

The Roku client should show channel numbers, similar to how the Web client does.

The major places that could be improved are:
1) Include channel number on the guide listing for each channel Moved to #2025

2. Include channel number in the episode details for a Live TV channel
   i.e. The Web client
   

3. Include channel number in the OSD when viewing a Live TV channel
   i.e. The Web client
   

Describe alternatives you've considered

Additional context

Jellyfin Web Client and the built-in Roku app for watching TV broadcasts directly both include the Channel Number and a logo or call sign for each channel.
i.e. "1.1 XYZ" as opposed to just "XYZ" or an XYZ logo

Due to complexity of implementation, the first item was moved to a separate task: #2025
