Introduce `/api/rules/archive-by-tag` endpoint

[simonbyford]

What does this change?

Does two things:

1) adds some handling to the /api/rules/csv-import endpoint to ensure the user making the request has the correct permissions. Also stores their email address against the change instead of the dummy value "CSV Import" (see: https://github.com/guardian/typerighter/commit/b71cd93596dad8f5accb460bd9ede51e4cc386b8) 2) introduces a new endpoint /api/rules/archive-by-tag which can be used to bulk-archive rules based on a given tag (see: https://github.com/guardian/typerighter/commit/e62afe13cc6c4bf5edcde9d28cc078224ff0fbbd)

The new endpoint /api/rules/archive-by-tag accepts one parameter encoded as form-data:

• tag (required): the tag associated with the rules to archive.

For example:

curl --location 'https://manager.typerighter.gutools.co.uk/api/rules/archive-by-tag' \
--header 'accept: */*' \
--header 'content-type: application/json' \
--form 'tag="MP"'

How to test

It's slightly more complicated than the above. See these notes on the previous PR: https://github.com/guardian/typerighter/pull/477#how-to-test

Testing on CODE:

I'm not too sure why this particular request took 17 seconds. Subsequent requests took 200ms!
