Add download functionality for equipment attachments

- Introduced a new endpoint `GET /equipment/{id}/attachment/download` in the API for downloading equipment attachment files.
- Implemented the `downloadEquipmentAttachmentFile` function in the client to handle file downloads via the API, ensuring proper token management and blob handling.
- Updated the EquipmentAttachmentInput, EquipmentList, and EquipmentShow components to utilize the new download link, enhancing user experience by allowing direct downloads without exposing the MinIO URL.
- Added a new EquipmentAttachmentLink component to encapsulate the download link logic and improve code reusability.
