Configure topomojo.api as public client for Swagger UI (#57)

Make topomojo.api a public client to match the pattern used by all other
Crucible API clients (alloy.api, player.api, caster.api, etc.). This allows
the Swagger UI to authenticate properly without requiring client secrets,
which cannot be securely stored in browser-based applications.
