PR #10 added 000035_api_key_suffix and PR #11 separately added
000035_api_key_smart_limits, both targeting the api_keys table.
golang-migrate refuses to load when two source files share a
version number, so the backend container failed health checks
in fresh stacks.
Bumping api_key_smart_limits to 000037 keeps PR #10 in its
original slot (it landed first) and matches the next free
version after 000036_contact_categories. The two migrations
touch different columns so apply order does not matter.
