Fix AI chat re-renders and refactored code (#18585)
This PR: 

- Breaks useAgentChatData into focused effect components (streaming,
fetch,
init, auto-scroll, diff sync)
- Splits message list into non-last (stable) + last (streaming/error) to
prevent full re-renders on each stream chunk
- Adds scroll-to-bottom button and MutationObserver-based auto-scroll on
thread switch
- Lifts loading state from context to atoms
- Adds areEqual to selector
factories

We could improve further but this sets up a robust architecture for
further refactoring.

## Messages flow

The flow of messages loading and streaming is now more solid. 

Everything goes out from `AgentChatAiSdkStreamEffect`, whether loaded
from the DB or streaming directly, and every consumers is using only one
atom `agentChatMessagesComponentFamilyState`

## Data sync effect with callbacks new hook 

See
`packages/twenty-front/src/modules/apollo/hooks/useQueryWithCallbacks.ts`
which allows to fix Apollo v4 migration leftovers and is an
implementation of the pattern we talked about with @charlesBochet

We could refine this pattern in another PR.

Why Twenty

We built Twenty for three reasons:

CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.

A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.

We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
