[FIX] sheetview: pageUp/Down with frozen rows

## Description

There was two issues with the commands `SHIFT_VIEWPORT_UP/DOWN` when some rows were frozen:

- the viewport was never scrolled all the way down to the last row with pageDown
- pageDown/Up scrolled more than a "page" (the size of the viewport)

This commit fixes both issues.

Also replaced calls from `getActiveMainViewport` to `getMainInternalViewport`
in the plugin `SheetView` as it needs slightly less computations.

- [ ] undo-able commands (uses this.history.update)
- [ ] multiuser-able commands (has inverse commands and transformations where needed)
- [ ] new/updated/removed commands are documented
- [ ] exportable in excel
- [ ] translations (\_t("qmsdf %s", abc))
- [ ] unit tested
- [ ] clean commented code
- [ ] track breaking changes
- [ ] doc is rebuild (npm run doc)
