Fix CI linter errors: initialize clients, add missing imports, and fix variable scope

- Add time import for sleep() function
- Add default_gmail_api_scope variable before use in gmail_api config
- Initialize clients dict with retry loop before processing (lost in merge)
- All 10 ruff linter errors resolved (F401 unused imports, F821 undefined names)
