Add green-bean inventory and cupping features

Ports inventory management and SCA-style cupping scoring from
hope_roaster: lot tracking with audit-logged consumption, cupping
sessions with server-authoritative scoring and a live radar chart,
and links from the planner (draw-from-lot, open-cupping-session).

Also fixes the Blend/Single-origin toggle layout, replaces tooltips
with an in-context "why" teaching layer, and stages the planner UI
into pre-roast vs. post-roast phases.
