[FIX] l10n_cz: remove duplicate Tax ID (DIČ) on invoice header

Coresaas-18.3l10n_cz

This update corrects a display issue where the Tax ID (DIČ) was appearing twice on Czech customer invoices. The fix removes a duplicate entry from the invoice template, ensuring accurate reporting and compliance with Czech regulations. This improves the user experience for customers in the Czech Republic.

Original PR description

**Steps to reproduce:**
* Install the **l10n_cz** module.
* Create a customer invoice for a Czech company.
* Print the invoice.

**Observed behavior:**
* The **Tax ID (DIČ)** is displayed **twice** in the invoice header in default layout.
* **VAT** is displayed **twice** in the invoice headed in folder layout.

**Cause:**
* The `registry_vat_external_layout` template adds `company.vat` to `company_address_list`.
* Base external layouts already include `company.vat` in the same list.
* This results in duplicated DIČ rendering.

**Fix:**
* Remove the redundant VAT `<li>` from `registry_vat_external_layout`.
* Keep only the Czech-specific **Company ID** (`company_registry`) entry, which is not provided by base layouts.

[FIX] base: truncate long filenames for binary stream

PR #262354

Coresaas-18.3base

This update resolves a technical issue where long descriptions in related images on Sales Orders could cause website errors. The fix truncates excessively long filenames for binary streams to prevent exceeding Nginx's buffer size, ensuring images load correctly. This improves the user experience for Sales Order editing.

Original PR description

## Problem:
When generating a filename for a related studio image field, if the `name` is excessively long, the response header may exceed nginx's buffer size of 4kb, causing the request to fail.

## Solution:
We will truncate the assigned filename for binary streams to the first 255 characters of whatever the assigned name would have been.

## Steps to reproduce (Runbot 18):
1. Open Studio editor on a Sales Order
2. Edit List View on Sale Order Lines
3. + Related Field, Product > Image, image widget
4. Make the description very long (close to 4000 characters)
5. Note the image will not load for that SOL, and the network tab shows a 502 error
