## Problem
`EnableBankingProvider::getTransactions` returned 422
`DATE_FROM_IN_FUTURE` when an account had a future-dated last
transaction (e.g. pending/scheduled). `linkedDateFrom` was set from
`lastTransaction->transaction_date` without bounding, producing
`dateFrom > dateTo`.
Sentry:
[PHP-LARAVEL-15](https://whisper-money.sentry.io/issues/PHP-LARAVEL-15)
## Fix
Clamp `linkedDateFrom` to `dateTo` (today) in
`SyncBankingConnectionJob::syncEnableBanking`.
## Tests
Added test covering future-dated last transaction case.
Fixes PHP-LARAVEL-15
