SimpleChatTCRV:UICleanup: Use chat_uirefresh not chat_show

Rename chatmsg_ui_refresh to chat_uirefresh.

Even in case of the delete path and inturn deleting one of the last
two messages in a chat session, now use the generified chat uirefresh
logic instead of the chat_show full session refresh / recreation of
the session ui

Inturn to make the uirefresh really generic and usable in all cases
including above case, now take care of clearing the tool call edit
/ trigger at the beginning, so that the last 2 messages decide in
turn whether to show a tool call edit/trigger ui or not, as well as
the tool call response edit / submit ui.

 Make chat show messages by default only appends new chat messages to existing list of shown messages in ui,

 implemented, need to cross check.

-With the new optimized limited ui update based flow, avoid duplicate chat message ui blocks.
