Cooking assistant's fullscreen mode gets a real left sidebar (always-
visible conversation list, hover-reveal rename/delete) on desktop
(md+), replacing the small dropdown menu that made sense in the narrow
420px drawer but not in a full-viewport layout. Mobile fullscreen and
the normal drawer keep the dropdown (ConversationMenu) — no room for a
persistent sidebar there.
Extracted the shared fetch/rename/delete/create logic into
use-conversation-list.ts so the dropdown (ConversationMenu) and the new
sidebar (ConversationSidebar) can't silently diverge — both are thin
render layers over the same hook. ConversationMenu gained an optional
className prop so the panel can hide it with `md:hidden` specifically
when the sidebar is already covering that job.
Per-recipe chat is untouched — it's single-threaded by design and never
used either of these components.

Both buttons were opacity-0 group-hover:opacity-100 — no touch equivalent
to :hover, so they never appeared on mobile at all. Made them always
visible, matching the app's existing convention for per-item actions in
narrow lists (e.g. shopping-list-actions-menu.tsx) rather than hover-reveal.

The general assistant had exactly one conversation per user forever
(recipeId null on chat_messages) — no way to start fresh or organize
by topic. Adds an ai_conversations table (title, timestamps) and a
nullable conversationId FK on chat_messages; the assistant panel gets
a conversations menu to create/switch/rename/delete, auto-titling a
new conversation from its first question.
Per-recipe chat is untouched — each recipe already has one natural
thread, so multi-conversation support only applies to the homepage
assistant. Pre-existing general messages (no conversationId) aren't
migrated into the new model and won't appear in the conversation list.
Requires migration 0042 to run against a live DB — not applied in
this sandbox (no Docker here); run `pnpm db:migrate`.
