Summary of Changes

_Continuation of the work in #48770 _
Replace manually inserted left-to-right unicode marks (LRM) with HTML bidirectional isolation using the element where appropriate. This follows the recommendation of the w3c multilingual site.

Joomla currently uses invisible Unicode directional marks (‎) in several places to influence the display of text in right-to-left (RTL) languages.

These marks can affect the ordering of adjacent text, but they do not provide proper isolation of the content. This can lead to unexpected behaviour when displaying mixed-direction text.

HTML provides the element specifically for this purpose. It isolates a piece of text from its surrounding content and allows the Unicode bidirectional algorithm to determine its direction independently.

Using provides a semantic HTML solution rather than relying on manually inserting invisible formatting characters into strings.

Testing Instructions

Set the administrator language to a genuine RTL language, such as Arabic or Hebrew.
Check the affected areas where dynamic values are displayed alongside RTL text.
Verify that values such as upload-size limits and version information display in the expected order.
Repeat the checks using an LTR language to ensure that the change has no adverse effect.
