f_hutch_cam used XF:27IDA-BI{GigE-Cam:5}. The hutch-f-cam IOC (ioc_host_vars xf/hex/xf27id1-cam1.nsls2.bnl.gov/hutch-f-cam.yml) serves XF:27ID1-ES{GigE-Cam:5}, so the camera worked in CSS but not in bluesky (reported by Zhong).

• Fixes the prefix in profiles/collection.py and in the GUI's camera list.
• Adds tests/test_device_prefixes.py, which pins each IOC-served detector/camera prefix (profile and GUI) to its IOC's PREFIX. It fails on the first commit and passes on the second. The other prefixes already matched.

Verification: mock/unit tests (652 passed, pyright clean). At HEX, from xf27id1-ws2 (read-only): caget 'XF:27ID1-ES{GigE-Cam:5}cam1:Model_RBV' → GT2460; the old prefix is not found. After merge: await f_hutch_cam.connect() at the beamline.
