- trees.py: change account_id=current_user.account_id →
account_id=tree.account_id so super-admin cross-account shares land in
the tree's tenant where RLS will see them.
- migration a05e1a1bea7c: fix backfill to join tree_shares → trees instead
of tree_shares → users(created_by). Same logic: historical shares belong
to the tree's tenant.
- test_tree_sharing.py: add test_share_account_id_matches_tree_not_actor
to assert share.account_id == tree.account_id after POST /share; also
add missing account_id to all direct TreeShare(...) constructors in
existing tests.
- test_phase1_migrations.py: remove team_id= from TargetList constructor
(column dropped in Phase 3).

P3-A: Add account_id to audit_logs model + migration (backfill via user_id →
users.account_id). log_audit() gains optional account_id param with fallback
SELECT to avoid churn across 40 call sites.
P3-B: Add account_id to tree_shares model + migration (backfill via created_by
→ users.account_id). TreeShare constructor updated in trees.py.
P3-C: Enable RLS on 6 remaining tables: step_ratings, step_usage_log,
target_lists, session_shares, audit_logs, tree_shares.
P3-D: Drop team_id from target_lists — endpoint, schema, and model now use
account_id as the sole isolation key.
P3-E: Append Phase 3 RLS isolation tests for all 6 tables.
test_target_lists.py: fix cross-account test to use Account model (not Team)
and set account_id on new User.
