feat(migrations): update franchise to percentage in tenant_insurances and tenant_service_coverage

- Changed franchise_rials to franchise_percent in tenant_insurances and tenant_service_coverage tables.
- Reset old rial values to 0/NULL as they are not convertible to percentage.

feat(command): add SeedInsuranceScenarioCommand for seeding insurance data

- Implemented a command to seed supplementary insurance contracts, patients, and claims for a specified doctor.
- Includes functionality for purging existing scenario data and generating new entries with predefined contracts and patient scenarios.
