* test(proxy): stop running real-DB tests in GitHub Actions unit jobs
GitHub Actions unit jobs were spinning up a Postgres service container, but
the only active tests that touched it either used the DB incidentally (a
cargo-culted prisma_client.connect()) or were genuine integration tests
mislabeled as unit. Mock the incidental ones so the proxy-db job needs no
container, and move the tests that genuinely need a database (proxy
management behavior, master-key-not-persisted, schema-migration sync) to
CircleCI, which is already the real-infrastructure lane.
* test(proxy): restore no-unexpected-startup-writes canary in master-key test
Greptile noted the hash-match assertion no longer catches other unexpected
startup writes (a default key, a rotation artifact). The CircleCI job gives
each run a fresh DB, so a clean startup must leave the table empty; add that
canary back alongside the precise master-key assertion.
* remove code block upserting master key hash to db
* run test to check if key upserted into db
* run ci/cd again
* litellm_proxy_security_tests
* litellm_proxy_security_tests
* run prisma entrypoint
* ci/cd run again
* fix test master key not in db
