Add a selectable text option to various note views. We don't want
selection events to interfere with back drag, so this is the first step
toward ensure back drag works.
Vertical scrollviews also interfere with back drag, so we'll still need
a way to compose gestures. It's not clear if this is currently possibly
with egui (union of responses somehow maybe?)

We have a NoteRef cache for threads in memory, which is just a list of
NoteKeys and timestamps.
When reopening a thread, query the local DB to see if there are any new
notes that we might have missed because we weren't actively subscribed
to them.
