[FIX] l10n_it_pos: prevent printer deadlock

PR #121987

Enterprisemasterl10n_it_posHIGH

This change prevents the Italian POS fiscal printer from getting stuck after the first receipt is printed. It removes a conflicting printing path and aligns the settings so the receipt is sent in one reliable way, avoiding the need to reload the page during sales.

Module: l10n_it_pos

Steps to reproduce:
- In the POS settings, enable "Automatic Receipt Printing";
- Enable "ePos Printer" to make the "Skip Preview Screen" option appear;
- Disable "Skip Preview Screen";
- Disable "ePos Printer";
- Set up an Italian Fiscal Printer;
- Open a POS session and process a first order.

Issue: After the first receipt, no other messages (price display, receipt, open register) are sent to the fiscal printer. A page reload is required.

Cause:
When "Automatic Receipt Printing" is true but "Skip Preview Screen" is false, a race condition occurs. `afterOrderValidation` triggers a print job while simultaneously transitioning to the `ReceiptScreen`. When the `ReceiptScreen` mounts, it triggers a second fiscal print job before the first has resolved. This creates a deadlock in `toHtml` of  `renderService`, permanently blocking the printer queue.

Solution:
Since the italian localisation sending the receipt to the fiscal printer is mandatory, the printing route is now tied to the "Skip Preview Screen" option.
UI settings are adjusted to hide the redundant auto-print checkbox when an IT fiscal printer is configured.
