Add quick_ideas skill and job for Quick dinners (Feature 18)

quick_ideas v1 suggests Quick dinners of one kind, crockpot or under30,
from the household context, never returning a name already shown: the
exclude list is checked against normalized names with harness.Similar.
POST /api/v1/ideas/quick {kind, exclude[]} validates both fields (no
default kind) and answers 202 {jobId}; the quick_ideas job asks for 12
ideas, grounds them through the same GroundEach rounds as
ideas_from_ingredients and keeps up to 6 whose grounded recipe is of the
kind (crockpot: method crockpot; under30: minutes_total <= 30), so the
model's estimate never decides. Fewer survivors make a shorter page,
never a padded one.

The grounding loop, failure clearing and failed-result view are now
shared generic helpers used by both idea jobs rather than a second copy.
