fix: merge main into feature branch - resolve all 18 conflicts cleanly

Merges origin/main (v0.155.0) into the classification feature branch,
resolving all 18 conflicted files by accepting main's version and
re-applying only classification-specific additions:

- Renumber migration from 037 to 038 (chains from 037_user_sessions)
- Re-add ClassificationRuleModel to models.py, env.py, conftest.py
- Re-add classification_rules_router to api/__init__.py
- All session management, QR auth, and devices code preserved from main

Migration chain validated. 62 classification tests pass.
