remove mint-tmp.ts, committed by accident

a throwaway that mints an owner jwt for end-to-end testing. its cleanup
never ran because the command that created it timed out, and the next
`git add -A` swept it in. no secret in the file — it reads the signing
key at runtime — but a token minter does not belong in the tree.
