feat: Introduce client management and integration updates

- Added client_id field to StoreTenantRequest and UpdateTenantRequest for tenant management.
- Updated TenantResource to include client_id in the response.
- Created migration to establish clients table and link tenants to clients.
- Migrated existing tenant integrations to client_integrations table.
- Grouped specific tenants under a shared client (OnTicket) in a new migration.
- Updated seeders to reflect new client structure and relationships.
- Adjusted integration configurations to require client instead of tenant.
- Added tests for client integration functionality and ensured existing tests reflect the new client structure.
