* [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.

This adds a lightweight form of tracing to GTS. Each incoming request is
assigned a Request ID which we then pass on and log in all our log
lines. Any function that gets called downstream from an HTTP handler
should now emit a requestID=value pair whenever it logs something.

The migration that adds the `admin_account_actions` table did so at the
same time as adding indexes onto the new table. This code was ran inside
a `RunInTx` function, but the table creation did not use the transaction
reference, while the creation of the indexes did. This could cause a
race between the table and index creations, depending on the scheduling
order. If the table creation did not win the race, then the migration
would fail.
This changeset corrects the table creation to also be done inside the
same transaction as the index creation.
