feat: new acore_string editor

[Exitare]

Adds a new editor for the acore_string table for the section "Other texts".
I realized yesterday that there isn't an editor or at least search field for this table and decided to implement it.

since Angular 14 we can access protected attributes also from the template, so there is very rarely a reason to use public and when we don't it's just because it's old code :)

Suggested change

	override readonly editorService = inject(AcoreStringService);
	protected override readonly editorService = inject(AcoreStringService);

This change causes this error:
TS2415: Class AcoreStringComponent incorrectly extends base class SingleRowEditorComponent
Property editorService is protected in type AcoreStringComponent but public in type SingleRowEditorComponent<AcoreString

And changing the editor causes a follow up issue.
IMO; this is a separate problem to be addressed

Your code looks very good! Thank you very much for this contribution. I've just left a couple of minor suggestions here and there. I hope I will have some time soon to test this PR and then we can merge it! <3
