Add Tähteet, and the real household dish list

Tähteet is leftovers. It is not food: it exists so a day can be recorded as
"we ate what was already there" without inventing a meal nobody cooked.

Modelled as a row flagged `special` rather than a nullable main_dish_id on
the log, so every foreign key and join carries on working. Migration 0002
creates it; the household never adds, edits or deletes it, and it never
appears in the catalog. It is loggable exactly like a real meal and sits on
the board apart from the categories, muted and at fixed size — it will be
among the most-logged entries and should not tower over the actual cooking.

It carries no category, which is why it could not be an ordinary main: those
must have at least one. That also exposed a bug in CategoryKey, which
returned the mixed Sekalaiset mark for anything that was not exactly one
category — so *no* categories drew the same icon as *several*. Zero now means
not food and gets its own mark, a lidded tub in grey rather than a category
colour. The fix reaches the board, the sides step, the logged card and the
history at once, since they all ask the same function.

PRD §6 records the hard requirement: the stage 2 suggester must never propose
it, so cooldown, coverage and weighting all skip it despite how often it is
logged.

The seed bundle is now the household's real list, taken from a JSON file
written in December 2024: 37 mains and 9 sides. Letut and Pannari were
dropped as not being dinners, Kanakintut folded into Broilerin koipireidet,
and has_sides assigned by rule — soups, casseroles, laatikko, kiusaus,
risotto and pasta dishes take none; sauces, patties and roasts do.

Two tests failed immediately on the migration because they hardcoded id 1,
which the new row now occupies. Moved clear of it.

+**not food**: it exists so a day can be recorded as "we ate what was already

+- No category, which is why it cannot be an ordinary main: those must have

+- Created by a migration. The household does not add, edit or delete it, and

+- Loggable exactly like any other entry, and shown on the log board apart

+- **The stage 2 suggester must never propose it.** It is excluded from the
