Remove non-strict Mastodon smoke test

The non-strict variant only exercised plain HTTP without signature
verification, which no longer reflects how Fedify is used against real
fediverse servers.  The strict variant (HTTPS + HTTP signature
verification via Caddy TLS proxies) is now the sole Mastodon smoke
test.

Renamed the strict files to canonical names so the layout matches the
other service smoke tests:

 -  docker-compose.strict.yml → docker-compose.yml
 -  provision-strict.sh       → provision.sh
 -  mastodon-strict.env       → mastodon.env
 -  smoke-mastodon-strict.yml → smoke-mastodon.yml
