Refresh VCRs

[ajtucker]

The VCRs (recorded HTTP traces) used in the tests date back as far as 2020 and need updating.

• Tests still use fsa-rp-test.epimorphics.net. Change to fsa-dev-rp.epimorphics.net
• Requests for //regulated-products/ 404 due to double slash.
• Some requests require a local UV API running and UV no longer exists, so these tests need to be refactored to use a different API or removed if they can no longer be tested.
