Chat with groups + AI chat UI and logic overhaul

[InAnYan]

Changes include:

1. AI chat UI - separated to components (easier to handle and modify AI chat code)
2. Any kinds of errors while chatting and file ingestion are now stored in notifications (button in AI chat in lower left corner) - simplifies code, user flow and will be useful for groups.
3. Chat history is maintained differently. It's now a simple ObservableList<ChatMessage>, so for every BibEntry there is a chat, and it's easy to get that chat. So chat history is separated in a facade ChatHistoryService, that works fine while running JabRef, and an implementation ChatHistoryImplementation, implementation is responsible for loading and storing chat history.
4. Introduced IngestionStatus and IngestionService: that way we could easily monitor the state of ingestion.
5. Intro

There are problems with PR:

1. It's buggy (but I think they are solvable).
2. Notifications panel was not discussed with mentors (so it's a brand new idea), and it looks clunky.

can you show some screenshots?

I'm only one step towards chat with groups. The last push won't compile, just because, I need some rest :)

[InAnYan]

Okay, now PR is working.

When I finally add this group chat window I will refine the PR.

(Just one step left)

Is this missing task icon an issue of this PR or a general JabRef one?

it's a general issue (I think) https://github.com/JabRef/jabref/issues/11572

[InAnYan]

Okay, chat with groups is here.

Now, the PR should be tested thoroughly and polished...

[InAnYan]

Yay, more new code!

I did something terribly wrong with Git

(But it seems it's all right)

From UI perspective, https://github.com/InAnYan/jabref/issues/169 is kind of blocker, but it seems to be unfixable for now. Thus, we go ahead and fix later.
