Introduced a new `ReadDocumentDetailsQuery` to fetch document
metadata (`DocumentDetailsDto`) without the binary payload.
Updated `MappingProfile` to map `Document` to `DocumentDetailsDto`.
Refactored `DocumentService` to handle separate fetching of
metadata and binary data, combining them into `DocumentDto`.
Changed the metadata endpoint to `/api/Document/details`.
Added a new `GetDocumentDetails` endpoint in `DocumentController`
to return metadata without binary data. Updated
`EnvelopeReceiverPageDataService` with a new method
`GetDocumentMetadataOfSenderAsync` for fetching metadata.
These changes improve efficiency by allowing clients to load
metadata without transferring large binary data when unnecessary.

- Refactored boot overlay removal logic in `App.razor` into a reusable function `sfRemoveBootOverlay`.
- Simplified event handling for overlay removal and fallback logic in `App.razor`.
