Add Docker support and enhance data models for tender details

- Introduced a .dockerignore file to optimize Docker builds by excluding unnecessary files.
- Updated the Dockerfile to use a Flutter base image, enabling web builds for the application.
- Added new data models for `Lot` and `OrganizationAddress` to represent tender details more accurately.
- Enhanced the `Organization` model to include `companyId` and a nested `address` field.
- Updated the `TenderData` model to include new fields such as `noticeTypeCode`, `formType`, and `lots`, reflecting the API response structure.
- Regenerated necessary code for data models to ensure compatibility with the updated structures.
