feat: add unit mapping functionality

- Added new API path for unit mappings in `api_paths.dart`. - Implemented `upsertUnitMapping` method in `ImportRepository` to handle unit mapping creation. - Updated `ReceiptImportTab` to learn and save unit mappings during receipt import. - Created DTO for unit mapping with validation in `create-unit-mapping.dto.ts`. - Added SQL migration for `UnitMapping` table creation with necessary constraints.
