* Renders avatar icons for [androidx.core.app.Person] icons in MessagingStyle notifications and for conversation

* shortcuts. Two shapes give conversations a recognizable identity at a glance:

* - a **wide pill** for people / direct messages (holds the node initial or short name), mirroring the in-app node

* chip, and

* - a **rounded square** for channels (holds the channel number),

*

* both filled with the caller-supplied colors (node colors for people, a channel-derived color for channels).
