chihlasm e05472615b feat: tenant isolation Phase 3 — audit_logs, tree_shares, remaining RLS
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.

"""Enable RLS on Phase 3 tables.
Tables covered:
- step_ratings (account_id NOT NULL since migration 7167e9374b0c)
- step_usage_log (account_id NOT NULL since migration 7167e9374b0c)
- target_lists (account_id NOT NULL since migration 2c6aabd89bc6)
- session_shares (account_id NOT NULL since session_share model)
- audit_logs (account_id NOT NULL since migration 2a9056eddd90)
- tree_shares (account_id NOT NULL since migration a05e1a1bea7c)
All use a standard intra-tenant isolation policy.
Token-based access to session_shares and tree_shares goes through
endpoints that use get_admin_db (BYPASSRLS), so a strict tenant
policy here is correct.
