Subject: [PATCH] fix: opening or reloading the new chat page shows no model
 and ignores URL parameters (#33459)

Opening or reloading the new chat page or a folder's page showed "Select a model" in place of the default model, ignored URL parameters such as models=, model= and q= (which fills in the message), and a message sent from there got no reply. Now the default model or the one from the URL is selected and the URL parameters apply, whether you open the page directly or come from another chat. Opening the Inbox and coming back still keeps the typed message and the chosen model.

Fixes #33457
