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.

+// AI-NOTE (for PR reviewer): This widget was rewritten to render ONLY the
+// backend-driven fields requested for the tender-details page (notice type,
+// form type, languages, issue/publication dates, procedure, value, duration,
+// deadlines, buyer org/address, lots, status, ids). Design is unchanged — it
+// still uses InfoItem/DeadlineItem. The _infoItem() helper returns an empty
+// list when a value is null/blank so empty fields don't render as blank rows
+// (this is why each entry is spread with `...`). The old hard-coded
+// "Reference Number" row was dropped because it isn't in the requested set.
