Transaction CSV export with currency columns

xpenser can now export the transactions behind the current view as a CSV file.

The export action lives in the View settings menu and asks which currency columns to include. It starts with the active display currency selected, then lets users choose from their default currency and favorite currencies.

What changed

• Added CSV export for the current filtered transaction view.
• Included transaction metadata such as category, vendor, tags, notes, scan attachment fields, dates, and original amounts.
• Added one amount column per selected currency.
• Converted each transaction using the exchange rate for that transaction date.

Why it matters

Exports are most useful when they preserve context. A spreadsheet row should not make users reconstruct the category, vendor, tag, note, or exchange-rate details from another screen.

Historical conversion also matters for multi-currency finance tracking. The CSV should reflect the value on the day the transaction happened, not today's exchange rate.

Where it fits

This improves audit, accounting, and spreadsheet workflows for xpenser users who want their open-source expense tracker data outside the app.
