feat(fusion_accounting_core): shared-field-ownership for cron_last_check

Declare account.bank.statement.line.cron_last_check on
fusion_accounting_core so the column survives Enterprise
account_accountant uninstall. Mirrors the existing pattern used
for account.move and account.reconcile.model shared fields.

- Add models/account_bank_statement_line.py declaring cron_last_check
  as fields.Datetime(copy=False)
- Wire model into models/__init__.py
- Add post_install regression test verifying field presence and type
- Bump manifest 19.0.1.0.0 -> 19.0.1.0.1
