Acceptance Criteria:
When a user has initiated an OCR engine on a proofread page, the loading state appears as follows:
1. the page body text field is disabled
2. a loading icon along with "OCR in progress..." appears on the top left corner of the page body text field
3. a "Cancel" button is added next to the "OCR in progress..." status, in case the user wants to terminate the OCR process early.

Note:
Depending on the verb that we end up with-- "Extract" versus "Transcribe" we will have "Transcribing" instead of "Extraction" in the illustrative image above. This should not impact complexity
If there's already text in the box, will it have a background of its own? May need its own color for readability. Whole text gets grayed out for message.
There may be a loading icon in MediaWiki somewhere?
Could also be a progress bar, but that would be too much
