Root cause: sync_account_priorities_for_upstream() was doing a global
priority re-rank across ALL imported accounts on a website whenever any
upstream rate changed, triggering spurious account_priority_changed
notifications for accounts in different target groups with no competition.
Fix:
- Add imported_target_group_id / imported_target_group_name to
UpstreamGeneratedKey (nullable; old data falls back to group_id)
- Writ imported_target_group_id on account import in websites.py
- Rewrite sync_account_priorities_for_upstream():
* bucket accounts by competition_group = imported_target_group_id or group_id
* only process buckets with count > 1 (genuine competition)
* each competitive bucket independently sorted by rate; priority starts at 1
* single-account groups: completely skipped (no update_account, no notification)
* no competitive groups at all: early return, no log, no notification
- Remove auto priority update in re-import idempotency path (was also
incorrect; now fully delegated to sync_account_priorities_for_upstream)
- Fix Sub2ApiWebsiteClient local import in sync fn → use module-level name
so monkeypatch works correctly in tests
Tests: rewrite test_priority_sync.py
- REMOVED: test_priority_sync_full_website_update (was asserting the buggy behavior)
- NEW: test_no_update_when_different_groups_single_account_each
- NEW: test_same_target_group_two_accounts_updated
- NEW: test_two_target_groups_independent_priority
- NEW: test_old_data_null_target_group_fallback
- NEW: test_single_account_in_mixed_website
- UPDATED: test_priority_sync_log_structure (now requires competitive group)
- KEPT: test_priority_sync_cross_upstream_group, test_import_auto_priority_by_rate
All 25 tests pass (8 priority_sync + 17 existing upstream tests).
