Subject: Rewrite watchlist as custom HTML component with proper styling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaces st.button rows with a components.html iframe that renders sym·price·Δ%
in a 3-column grid with hairline dividers, monospace fonts, and colored change
percentages. Adds hidden text_input click receiver so row clicks update
session state. Fixes toggle button to show toast when watchlist cap is hit and
removes now-redundant psm-watch-toggle CSS.
