Language path prefix breaks method ParagraphBlocksEntityManager->getRefererEntity

Problem/Motivation

Using Paragraph Blocks with enabled translations and path prefixes like 'en' lets method ParagraphBlocksEntityManager->getRefererEntity() always return null because the path prefix isn't respected and the subsequent method ParagraphBlocksEntityManager->getEntity() cant find the entity.
This in turn leads to less useful block labels presented by Paragraph Blocks in Layout Builder node override forms, because all lack the admin title provided by Paragraph Blocks

Steps to reproduce

1. configure Content Translation and language path prefixes
2. use Layout Builder and allow custom node layouts
3. use a nodes layout form on a node with paragraph blocks and also admin titles added to it
4. in place block form only shows paragraph block names like 'Paragraph type item 0'

Proposed resolution

I looked into the ParagraphsBlockEntity and propose a rewrite of this class.

Remaining tasks

Probably more refactoring of the whole entity manager structure might be useful.
