feat(clerk): add collection flow — multi-DR savings to CR GL with maker-checker

- Transaction entry: detect collection mode (N DR savings → 1 CR GL) and disbursement mode (1 DR GL → N CR savings); build dbCr-tagged payload for backend
- Disbursement review: show 'GL Credit (Target)' / 'Debit Entries' labels for collection; fix double-count by summing only DR entries for collection totals; dynamic approve button text
- My disbursement requests: add DR/CR badge column in expanded credit-entries preview
- My requests / withdrawal-requests: minor consistency updates
