feat(fusion_accounting_bank_rec): migration audit PDF report

QWeb PDF showing per-company: backfilled precedent count, pattern count,
remaining unreconciled bank line count. Bound to fusion.migration.wizard
so it appears in the Print menu after migration runs.

- reports/migration_audit_report.py defines the AbstractModel
  report.fusion_accounting_bank_rec.migration_audit_template, which
  aggregates per-company counts from fusion.reconcile.precedent
  (source='backfill'), fusion.reconcile.pattern, and
  account.bank.statement.line (is_reconciled=False).
- reports/migration_audit_report_views.xml is the QWeb template.
- reports/migration_audit_report_action.xml registers the
  ir.actions.report bound to fusion.migration.wizard.
