770 (rwxrwx---) is more secure - only owner and group can access, excluding 'others'.
The service user can still access because it's added to the user's group via:
usermod -aG shellUsername serviceUser
The real fix was wrapping chmodSync in try/catch in email-db.ts so it doesn't
crash when trying to chmod files owned by other users.
Consistency fix with src/servers/api/users/provision.ts which was updated to use:
- chmod 775 (rwxrwxr-x) instead of 770 (rwxrwx---)
- Recursive chmod to fix all subdirectories
This allows the service user (in the user's group) to read/write files
for background jobs like email sync.
Also added helpful comment explaining the permission choice.
