[Bakual]

Pull Request for Issue #24339

Summary of Changes

• Remove hardcoded reference to mod_multilangstatus in mod_status
• Remove no longer used helper class in mod_multilangstatus

Bringing the behavior back to a regular module.

Testing Instructions (before PR)

First Scenario when language filter plugin is disabled:

• Try to enable the multilanguage status module and assign it to a position (eg "status")
• Notice the not so nice appearance of the icon
• Refresh page
• Module icon gone again

Second scenario when language filter plugin is enabled:

• If you did the first scenario, you now have two multilang icons
• Try to disable the multilanguage status module in the module manager
• First icon vanished, second one still visible
• Refresh page
• Both icons visible again. Module published again in the manager

Expected result

Bevahior like any other module

Actual result

Prior to PR: It seems to be living and doing its own thing 😨

After PR: Regular behavior:

• If module is assigned to a position and published -> appears.
• If module is not assigned to a position and/or not published -> doesn't appear.

@Bakual Assuming that I am reading this correctly this PR is no longer relevant. I am closing it at this time. If I am mistaken you can always re-open it
