feat: replace several files with a sqlite db (#3128)

These files have been known to have corruption issues. SQLite will
perform better across filesystems for reads/writes across threads, and
will lock as expected.

I've also put the session file in there, though I'm 50/50 on it - I'll
be replacing it with keyring storage asap anyway.

The key file is _not_ included. It should ~never be changed, and should
be easy for the user to secure + manage themselves

In the future, instead of creating more files, we can just use this as a
kv store
