test(serve): isolate Bedrock model-import integ tests behind import_model marker

The "Concurrent model import jobs" Bedrock quota is fixed at 1 and not
raisable. Running these tests in parallel under PR checks (-n auto) makes
them collide on the quota and flake. Register a new `import_model` pytest
marker and tag the four import-job tests so they can be split out of PR
checks into a dedicated serial scheduled run.
