Removable reference curves, audit fixes across pages, shaded Academy art

The planner's Artisan .alog drawer now shows what's attached with a
"Remove reference curve" control (re-rendered per drawer open), so adding
a reference curve is no longer a one-way door; /api/alog shares the 8 MB
body cap so real-sized logs parse instead of failing with "bad_request".

Deep-evaluation fixes: editing a brew of an archived bean no longer
silently detaches the bean; the roasts pending-review poll no longer
wipes in-progress after-roast edits; roasters gain an Edit (rename/model)
action; the gear page refuses to autosave over a failed load; duplicating
a plan carries its custom name; cupping sessions can attach a plan after
creation (ownership-checked PUT + selector); admin user deletion also
refreshes plans/audit; cupping cup-count subtitle stays live; roasts
error-row colspan corrected. Regression tests cover the new cupping PUT
and the /api/alog body cap.

Academy scenes drop the flat paper-cutout look: shared defs provide
radial-gradient shading on every bean/half-bean/particle, flame gradients
with radiant halos, soft ground shadows, and a warm-lit stage background;
fill-shift animations now ride a partial-opacity tint overlay so shading
survives the color change.
