Chat

• Now it's own tab (Memories is now with speech profile and identifying others)
  • Updated way to send messages through (currently only used in goal widget)
  • separated the chat bar out and rewrote movement logic to handle all four states (microphone shown/not shown and hardware keyboard connected/disconnected)
• removed apps button in favor of new chat app dropdown and new chat button
• Now using "Chat Apps" instead of "Apps" and "Chat Assistants" to be less confusing.

Code Review

This pull request successfully refactors the application to feature a dedicated "Chat" tab, improving user navigation and experience. The changes are comprehensive, including updates to the home page, chat page, and navigation logic from other parts of the app like the goal tracker and app details. The introduction of a new chat app selector in the app bar is a nice touch.

I've identified a critical bug related to a type mismatch that could cause a crash, a high-severity design issue regarding state management that could impact maintainability, and a violation of a repository rule for color opacity. Addressing these points will improve the code's correctness and robustness.
