feat: add database details section to settings

Shows path to database (click to copy), database size, database log
size, message count.

Also adds a Ctrl+Shift button to wipe the database permanently. This is
performed by clearing the Messages collection and then rebuilding the
database, which brings it down to around 48KB on my machine (even with
many messages).
