Add field management module with database schema and validation

- Introduced `FieldModule` to manage cycles and plans, including read and write controllers.
- Created database migrations for `company_settings`, `cycles`, `cycle_weekdays`, `cycle_destinations`, `plans`, `plan_destinations`, `plan_invoices`, and `plan_packing_slips` tables, including constraints and unique indexes.
- Developed service and repository layers for handling cycle and plan data operations.
- Added unit tests for the cycles and plans services, repositories, and controllers to ensure functionality and correctness.
- Updated application module to include the new `FieldModule` for better organization.
