Add correct history storage

[e19166]

PR description

Summary

This PR improves how the chatbot conversation history is preserved when a user navigates between docs pages / versions. Before clearing the current chat session, the UI now snapshots the latest conversation and sends it to the parent docs page (when embedded in an iframe) so it can be stored as a saved session. It also updates the backend chat endpoint and removes unused authentication token handling.

Changes

• Add “latest messages” snapshot tracking
  • Introduces latestMessagesRef and keeps it in sync with messages via useEffect, ensuring the most recent conversation is always available even inside event handlers.
• Snapshot chat history before clearing
  • On navigation/hash change cleanup, captures current chat state (chatHistory from localStorage or fallback to in-memory messages) and posts it to the parent window via window.parent.postMessage.
  • Message payload:
    • type: 'chat-snapshot'
    • id: 's_' + Date.now()
    • state: { chatHistory: ... }
  • Wrapped in try/catch so failures are non-fatal.
• Clear local history as before
  • Continues to abort any inflight request, clear localStorage.chatHistory, and reset UI state.
• Remove auth token usage
  • Deletes authService import and access-token retrieval.
  • Removes conditional Authorization: Bearer ... header injection.
• Update chat service endpoint
  • Switches the fetch URL.

Motivation / Problem

Previously, clearing localStorage on navigation could cause the active conversation to be lost before the parent docs site had a chance to persist it as a saved session. This change ensures the current conversation is captured and handed off to the parent container before being cleared.
