feat(customers): enhance customer retrieval with filtering options

- Updated `findAll` method in `CustomersController` to accept filtering parameters.
- Implemented filtering logic in `CustomersService` to retrieve customers based on type and search query.
- Added `PosCustomerFilterDto` for query validation.
- Updated customer-related DTOs to make fields optional and added length validation where necessary.
- Modified customer-related logic in `sales-invoice-tsp.utils.ts` to accommodate new DTO structure.
- Added unique constraints to `customer_individuals` and `customer_legal` tables in the database migration.
- Removed commented-out code in `PosMiddleware` for cleaner codebase.
- Set default value for `is_default_guild_good` to false in `OwnedGoodsService`.
