IQSS/7687-Curate command updates

[qqmyers]

What this PR does / why we need it: Fixes a bug where the Curate (update an existing published dataset) command, usable by superadmins, didn't correctly update the file access request allowed flag if it was changed in the update. The PR also include a couple other fixes updates - at QDR, file name updates were being dropped, noticed after the equivalent of #7337 was merged. Also changing the permission annotation (see issue discussion).

Which issue(s) this PR closes:

Closes #7687

Special notes for your reviewer: The file access request issue was just discovered and I've verified the fix at QDR. The change to add a merge of the datasetversion makes sense, but I'm just catching up from last year on that and my notes indicate that I thought some change related to #7337 could be involved, but it's possible that the problem affects develop.
W.r.t. addressing legacy db issues - I hope use is fairly rare and that if there were any name issues, those would have been caught/reported. The file access flag was more subtle, so easier to miss. As I noted in the issue, I'm not sure a flyway script makes sense but I could add a release note (that could either point to the query I listed that would help find instances and/or just point out that you can just do the update again to fix any affected datasets). Let me know what makes the most sense.

Suggestions on how to test this: Change the file request access flag in the Terms panel and update a file name, then use the Curate command and verify that Terms panel shows the flag update and/or that a restricted file acts as specified by the flag (requesting access is/isn't allowed), and make sure the file name changed.

Does this PR introduce a user interface change? If mockups are available, please link/include them here: no

Is there a release notes update needed for this change?: Some note along the lines of 'Bugs were found in the functionality allowing superadmins to update a published dataset version (without creating a new version) involving the Terms setting on whether to allow file access requests and with file name changes. If you have used this functionality, issue #7687 provides details and includes an sql query that will help in identifying any affected dataset.'

Looks good (and good catch!). I'll leave it to @djbrooke to determine what we include in the release notes (my vote is a reference to the issue could be enough).
