fix: cross-collection drag and drop tab and format issues (#7584)

Close the open tab when a request is moved to a different collection
via drag and drop, preventing the "Request no longer exists" error.

Add format conversion when dragging requests between collections with
different formats (.bru vs .yml). A new IPC handler parses the source
file and re-serializes it in the target collection's format. Folder
cross-format moves are blocked with a toast error.
