Remove confirmed-orphaned routes, handlers, and templatesHEADmaster

From the sitemap audit: /tabs/meals (same dead-tab pattern as the
removed /tabs/conditions, only reachable via ?tab=meals with no nav
button), /partials/lists (superseded by inline .Lists rendering in
trello-board.html), /shopping/toggle and /shopping/mode/{store}/toggle
(superseded by the one-way complete/filter model), plus the orphaned
trello-boards.html and error-banner.html templates that nothing
rendered or included. Rewrote the meals grouping test to exercise
groupMeals() directly since that logic is still live via the timeline.
