* Convert AccountViewHolder from Java to Kotlin
Use view binding in the converted code, which requires small changes in code
that calls constructors.
Pass showBotOverlays as a parameter, rather than having the code reach in to
the shared preferences, fixing a layering violation. This affects callers
and classes derived from AccountAdapter.
* Use 2-arg getString
* Simplify setting bot badge indicator
- Specify the drawable in the XML
- Use visible() to set visibility
- Rename ID to account_bot_badge to make it clearer that this is all it is for
* Use lateinit to avoid needing !! later
