fix: wildcard cors plus tweaks

[TateB]

changes:

• set cors origin to wildcard
• changed unregistered PUT behaviour to delete a registered media on an unregistered upload request
• removed goerli
• replaced usage of EnsPublicClient with ClientWithEns, importing functions when necessary.
  • results in a 41% decrease in gzipped worker size. lower worker size = faster response times since less code is evaluated
• added holesky in tests
• added image response cache header
