This fixes an issue where selected font sizes in mass mailing could be converted incorrectly, causing text to appear at the wrong size. The editor now uses the correct document context for calculations, improving consistency when editing email content.

Commit [1] introduced a responsive font size feature was. Following this, in the context of mass mailing, an issue arises when users select a font size from the toolbar dropdown. Specifically, the `_computePxByRem` function converts the `px` value selected by the user to the wrong `rem` value. This is because it relies on the font size of the `html` element of the main window's document rather than that of the iframe's document. Since the iframe's document has a font size of 14px where the main document has a font size of 16px, the conversion was faulty. Also, the value was cached on the window object, which is common to both documents. So this commit moves that cache to the document so two different values can be stored.

Task:3633405

A small bug fix was applied to the mobile mail module to correct a variable name typo that was introduced in a recent update. This fix also addresses a related issue with delayed notifications, ensuring mobile users receive their messages reliably.

Nothing big, just fixing a recent commit while fixing a related bug in community about delayed notifications.

This update resolves a test failure in the Point of Sale module that was causing automated testing errors. The fix removes reliance on demo data in the test, making the test more reliable and independent. This ensures the Point of Sale system continues to function properly during quality assurance checks.

Do not use demo data in test.

This update removes a deprecation warning that appears when users regenerate asset bundles through the debug menu. The system now uses the recommended cache management approach instead of an outdated method, ensuring the feature works smoothly without warnings in current versions.

Since [1] `model.clear_cache` is no longer recommended. Most models were changed besides the function responsible for regenerating asset bundles. This leads to a deprecation warning when pressing the button in the debug menu in 16.4+

This fix restores important version information that was accidentally removed from translation files in the Sales and Sales Stock modules. The version line is critical for the translation management system (Transifex) to properly track and manage translations, so restoring it prevents potential issues with the translation workflow.

This commit reverts an unwanted diff introduced by Commit[1]. Recently, Commit[1] introduced some wording changes within the portal layout, which required an update of the `.pot` file.

While the terms where correctly updated, Commit[1] also removed a line about the version of the project, which could cause some issue within Transifex.
