fix(formatter/sort_imports): Handle alignable comment with JsLabels

[leaysgur]

Fixes #17788

---

This bug occurred because there was no way to distinguish Text element between

• /* within TemplateLiteral
• and /* representing part of an alignable_comment

in IR elements.

Now made it detectable by wrapping it in a new label.

Pull request overview

This PR fixes a panic in the sort imports transform that occurred when template literals containing /* were incorrectly identified as alignable block comments. The fix introduces a new AlignableBlockComment label to explicitly mark actual alignable comments, allowing the sort imports logic to distinguish them from template literal content.

• Adds a new AlignableBlockComment label to track actual alignable block comments
• Updates comment formatting to wrap alignable comments with the new label
• Refactors sort imports logic to use label-based detection instead of text pattern matching

And I realized these labels are completely unnecessary when sort-imports is disabled!
I'll address this later as follow up PR.
