fix: improve native print output for dashboards and record tables (#22272)

## Summary

- Adds print-specific snapshots for dashboards so native browser
print/PDF captures charts and front components instead of the app shell.
- Adds record-table print snapshots for object index pages so printable
tables are generated from visible rows and native print avoids
virtualized blank pages.
- Preserves rendered chart layers by rasterizing canvas/SVG content for
print.

## Test plan

- [x] `yarn nx typecheck twenty-front`
- [x] `yarn nx build twenty-front`
- [x] Generated dashboard PDFs from the preview build and rasterized
pages to PNG for visual verification.
- [x] Generated Tasks/table-record PDFs from the preview build and
verified the final page contains table content instead of blank pages.
