Phase 0 Task 17. Installs a safety guard on ir.module.module that blocks uninstall of Odoo Enterprise accounting modules (account_accountant, account_reports, accountant, account_followup, account_asset, account_budget, account_loans) until the per-module migration flag fusion_accounting.migration.<name>.completed is set to True. Guard covers both button_immediate_uninstall (UI) and module_uninstall (CLI/API) paths, raising UserError with a pointer to the migration wizard and an escape hatch config parameter. Also ships a TransientModel fusion.migration.wizard as a shell: it detects installed Enterprise modules via GUARDED_MODULES and exposes action_run_migration for sub-modules to extend in later phases. No per-feature migrations are registered yet -- Phase 1+ sub-modules will hook in their own steps. Tests: TestSafetyGuard x2 pass (blocked-when-pending verified with account_accountant installed; not-blocked-when-completed verified by setting the flag). Made-with: Cursor
