Fixes #1117

Changes:

WORK FLOW:

• The 'Send Request' option is visible only to non-owners of the collection.
• Users can send sketch requests to any collection.
• Collection owners receive and review incoming sketch requests.
• Owners have the option to accept or reject each request.
• If accepted, the sketch is added to the collection with the original sketch owner's name.
• If rejected, the sketch is not added, and the request message is deleted.

WHAT'S HAPPENING UNDER THE HOOD:

• Upon every sketch request, a new schema named 'Message' is created, containing fields such as Request receiver, 'request sender', 'message', 'ProjectID', and 'CollectionID'.
• Both 'ProjectID' and 'CollectionID' are provided to the API as parameters.
• All messages are fetched based on the 'Request receiver' name.
• Each message includes the 'Request sender' name and the 'Collection' name.
• Upon acceptance, the sketch is saved to the collection depending on the 'ProjectID' and 'CollectionID'.
• All static words are retrieved directly from "translate.json" ensuring support for multiple languages.
