Timeline item sender profiles (#463)

* Adopt timeline item sender profiles for displaying user avatars and display names
* Prevent images from automatically being evicted from the in-memory cache when entering background
* Get rid of all the `urlString: String`s and start using proper URLs
* Add back manual display name loading as the sender profiles aren't working properly yet
* Implement a sender profile.
* Bump the RustSDK to v1.0.32-alpha
