* [chore] Remove years from all license headers
Years or year ranges aren't required in license headers. Many projects
have removed them in recent years and it avoids a bit of yearly toil.
In many cases our copyright claim was also a bit dodgy since we added
the 2021-2023 header to files created after 2021 but you can't claim
copyright into the past that way.
* [chore] Add license header check
This ensures a license header is always added to any new file. This
avoids maintainers/reviewers needing to remember to check for and ask
for it in case a contribution doesn't include it.
* [chore] Add missing license headers

store directly
* fix: use explicit local storage in tests
* feat: integrate s3 storage with the main server
* fix: add s3 config to cli tests
* docs: explicitly set values in example config
also adds license header to the storage package
* fix: use better http status code on s3 redirect
HTTP 302 Found is the best fit, as it signifies that the resource
requested was found but not under its presumed URL
307/TemporaryRedirect would mean that this resource is usually located
here, not in this case
303/SeeOther indicates that the redirection does not link to the
requested resource but to another page

for some other reason).
