CSV Export by Date Range

Hello,

Thank you for the great app — it’s very useful for tracking finances. I have one feature request that would make it even more convenient.

Currently, when exporting transactions via CSV, the app exports the entire archive. It would be very helpful if users could select a specific date range (for example, a particular month or custom period) when exporting transactions.

This would make data analysis and reporting much easier.

Thank you for considering this improvement.
