fix(ui): remove mobile bottom nav, unify processing indicator, and improve tooltip behavior on mobile (#632)

* fix: update tooltip component

* fix: remove the mobile navigation component

In addition,
- the sidebar is also updated to take full space
- the terminal shortcuts in shell are updated to not interfere with the
shell content.

* fix: remove mobile nav component

* fix: remove "Thinking..." indicator

In addition, the claude status component has been restyled to be more
compact and less obtrusive.
- The type and prop arguments for ChatMessagesPane have been updated to
remove the isLoading prop, which was only used to control the display of
 the AssistantThinkingIndicator.

* fix: show elapsed time only when loading
