Update draft folder structure to include account name

The draft folder path now includes the account name to prevent conflicts
when multiple accounts work on the same sheet. This requires updating
the draft_folder method signature and all call sites.

Additionally, account switching is now restricted when a sheet is in use
to maintain data integrity.
