Merge PR burnash#1515: Fixed APIError: [403] when copying permissions

This PR addresses issue burnash#1507 which caused a 403 error when copying permissions
from a spreadsheet located in a shared drive.

Key changes:
- Filters out folder-level permissions (organizer/fileOrganizer roles)
- Only copies permissions directly applied to spreadsheet files (writer, commenter, reader)
- Enhanced typing annotations to resolve mypy complaints
- All 141 unit tests pass successfully

Status: Safe to merge - narrowly scoped bug fix, well tested
