fix(savings): post GL entries for facility-charge collections at edit approval

Charges collected when a maker-checker Nominee/Digital-Feature edit is
approved deducted the account balance and appeared in the passbook,
but never posted a journal entry -- collectCharges() saved the charge
transaction directly and skipped the accounting bridge entirely, so
the GL never balanced against the subledger.

Also fixes an unrelated NPE this exposed: collectCharges() used
saveAll() instead of saveAllAndFlush(), so the new charge transaction
had no id yet when the journal-entry code tried to read it.
