refactor: Split company.controller.js into focused controllers

Split company.controller.js (461 lines, 5 concerns) into:
- company.controller.js: CRUD + email (134 lines)
- company-note.controller.js: note operations
- company-reminder.controller.js: reminder operations
- company-team.controller.js: user assignment operations

Update company.routes.js to import from new controllers.
