The /api/profiles handler re-imported _is_isolated_profile_mode locally inside
handle_get, which made the name function-local for the ENTIRE handle_get scope
-> the earlier use at the /api/projects branch (routes.py:8000) hit
UnboundLocalError (F823), failing 6 test shards + lint. It's already a
module-level re-export (routes.py:429), so the local re-import is redundant;
removing it lets every in-function use resolve to the module global. Also drop
an unused 'from pathlib import Path' in the new #4449 state-dir test.
