feat: Allow file and directory creation modes to be configured

The defaults remain the same as before.
For now, the config options are global instead of per-user.
Note also that the BoltDB creation maintains the old default mode of 0640
since it's not really a user-facing filesystem manipulation.
Fixes #5316, #5200
