This commit significantly refactors the `EditModelModal` component to streamline the user interface and enhance usability, aligning it with the interaction patterns found elsewhere in the application.
- **Consolidated Layout:** Merged the "Vendor Information" and "Feature Configuration" sections into a single "Basic Information" card. This simplifies the form, reduces clutter, and makes all settings accessible in one view.
- **Improved Prefill Groups:** Replaced the separate `Select` dropdowns for tag and endpoint groups with a more intuitive button-based system within the `extraText` of the `TagInput` components.
- **Additive Button Logic:** The prefill group buttons now operate in an additive mode. Users can click multiple group buttons to incrementally add tags or endpoints, with duplicates being automatically handled.
- **Clear Functionality:** Added "Clear" buttons for both tags and endpoints, allowing users to easily reset the fields.
- **Code Cleanup:** Removed the unused `endpointOptions` constant and unnecessary icon imports (`Building`, `Settings`) to keep the codebase clean.
