feat(fusion_accounting_reports): migration wizard bootstrap step verifies report definitions

Inherits fusion.migration.wizard from fusion_accounting_migration and
appends a _reports_bootstrap_step that confirms the 4 CORE report
definitions (pnl, balance_sheet, trial_balance, general_ledger) exist
after migration. Returns a structured result with expected, present, and
missing report types.

Hooked into action_run_migration via super(); failures are logged
(warning) but never raised, so the migration chain remains tolerant of
ordering between sub-modules.

Adds fusion_accounting_migration to manifest depends.

Tests: 1 new (test_migration_round_trip.py). Net 114 -> 115.
