Add finance giving demo data (#8102)

## Summary
Adds realistic finance/giving demo data to the demo data import system
so users exploring ChurchCRM can see populated donation deposits,
pledges, and giving history out of the box.

## Changes
- `src/ChurchCRM/Service/DemoDataService.php`: implement finance demo
data generation (deposits, pledges, giving records)
- `src/admin/demo/finance.json`: static demo dataset for finance records
- `src/skin/js/importDemoData.js`: wire up finance data import to the
demo data UI

## Why
The existing demo data import covered people, families, and groups but
left Finance completely empty. New users evaluating ChurchCRM had no way
to see what the finance module looks like with real data, making it
harder to assess the product.

## Files Changed
- `src/ChurchCRM/Service/DemoDataService.php`
- `src/admin/demo/finance.json`
- `src/skin/js/importDemoData.js`

## Testing
- Go to Admin Dashboard → Import Demo Data
- After import, navigate to Finance → verify deposits, pledges, and
giving records are populated
