chihlasm ad59446332 feat: user management — admin create, password reset, archive/delete, quick invite
Phase 1: must_change_password enforcement + change password endpoint/page
Phase 2: Admin user creation (M365-style) with temp password
Phase 3: Password reset (self-service forgot + admin-triggered)
Phase 4: User archive (soft delete) + hard delete with precheck
Phase 5: Quick invite from admin Users page

Also fixes:
- Auto-create subscription for accounts missing one
- Hard delete precheck ignores sole-member personal accounts
- Seed script patches tree nodes for validation compliance

Migrations: 031 (must_change_password), 032 (password_reset_tokens), 033 (user soft delete)
