Bulk Publish: Filter variant options to applicable cultures only (closes #19147)

[iOvergaard]

Summary

• When bulk publishing/unpublishing documents, the variant modal now shows only cultures that exist in the selected documents (not all system languages)
• Invariant document selections skip the language modal entirely and show a simple confirmation dialog
• Each culture option displays how many documents have that culture (e.g., "2 documents")
• All applicable cultures are pre-selected by default

Fixes #19147

Performance optimizations

• Fetch document items and languages in parallel using Promise.all (reduces initial load time)
• Defer notification and event context fetching until after user confirmation (no context overhead if user cancels)
• Extracted helper methods #publishDocuments/#unpublishDocuments and #reloadChildren for cleaner code
• Extracted the logic to build up the variants into a static method (mirroring the document-variant-language-picker element) to reduce duplication

Screenshot (before)

Listed all possible cultures so nothing was missing, did not reflect the actual state of the selected documents accurately:

Screenshot (after)

Shows only the selected cultures (English and German, but not Danish in this instance), pre-selects all of them.

Screenshot (after, only invariants selected)

Before, it would show the same as the "before" screenshot (all cultures), but now it knows that all of them are invariant and goes straight to the confirmation modal:

Hint: If you select both invariant and variant, we will have to show cultures, and in that case, the invariants will be listed under the default language

Test plan

• Select multiple invariant documents in a collection view → Publish → Should show simple confirmation (no language picker)
• Select multiple variant documents → Publish → Should show only applicable cultures with document counts
• Verify document counts are accurate per culture
• Test unpublish follows the same behavior
• Test mixed selection (some docs have en-US, some have de-DE) shows union of cultures

Pull request overview

This PR enhances the bulk publish/unpublish functionality in Umbraco CMS to show only applicable culture options for selected documents. Instead of displaying all system languages, it now filters the variant modal to show only cultures that exist in the selected documents, displays document counts per culture, and skips the language modal entirely for invariant documents.

Key Changes:

• Filters language options to show only cultures present in selected documents
• Adds document count display for each culture option
• Skips language modal for invariant documents, showing a simple confirmation instead
• Pre-selects all applicable cultures by default
