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 ProcessingInfo<I, O> for easy tracking of background processes (ingestion and summarization)
5. Things, that use serialization, were separated and split into an interface (...Storage) and implementation (MVStore...Storage). For each of the implementation there are tests
6. Now we can chat with a group of papers!

How to use the new "Chat with group" feature:

1. Enable AI features in the preferences at "File > Preferences > AI > General > Enable AI functionality"
2. Have a group with multiple entries with attached files.
3. Right-Click the group
4. Click the "Chat with group" button

Just first mall comments. 1k lines need more time to review

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?

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

it's a general issue (I think) #11572

[InAnYan]

Okay, chat with groups is here.

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

Yay, more new code!
