[5.0] Rework the com_messages message view

[wilsonge]

Pull Request for Issue #42124 .

Summary of Changes

Rework of the HTML structure towards something geared towards more input'less elements. Physically separates the invisible form from the rendered HTML content.

Testing Instructions

Whilst this ensures the view looks better in dark mode. It obviously changes the structure in light mode too. This too should be validated. Check with longer and shorter message lengths.

If we want to treat this like a form field we should use formal input fields with labels as @dgrammatiko mentioned, close this PR and once #42124 is amended merge that one

If we’re happy rendering this without form field style rendering we should merge this PR and maintainers or a release lead should decide which approach

[dgrammatiko]

FWIW I'm in favour of this one

@HLeithner Why not v5.0.1 as it is unreadable as of now in dark mode?

[HLeithner]

because the screenshots looks like only refactorying the html and no dark mode fixes

[brianteeman]

the html has to be refactored to enable the appropriate dark mode changes

[HLeithner]

thanks
