Implement three foundational schema features from the design doc:
- Tree forking with lineage tracking (migration 022): parent_tree_id,
root_tree_id, fork_depth columns with self-referential FKs and
composite analytics index
- Custom step enhancement: CustomStepSchema with source tracking
(ad-hoc, step-library, forked-tree) for backward-compatible JSONB
- Session sharing (migration 023): session_shares and session_share_views
tables with account-scoped visibility, cryptographic tokens, view
tracking, and allow_public_shares account policy
Includes 21 new integration tests (9 forking, 12 sharing), SaaS
consultant-recommended denormalizations, rate limiting on public share
access, and test fixture fix for invite code requirement.

Account.owner_id and User.account_id are both NOT NULL, creating a
circular dependency that prevents inserting either row first. Fix by:
1. Making owner_id nullable (set immediately after user creation)
2. Creating Account before User, then setting owner_id after flush
3. Removing NOT NULL enforcement on owner_id in migration 020

Transition from team-based to account-based multi-tenancy (Free/Pro/Team).
Migrations 016-020 create accounts, subscriptions, plan_limits, and
account_invites tables, then migrate existing users and content FKs.
New models: Account, Subscription, PlanLimits, AccountInvite.
Updated models add account_id alongside existing team_id (coexistence
for safe two-PR deployment). Permissions and deps refactored for
account_role instead of is_team_admin.
