feat(veckoplan): fyll alla maltider, variation, ratt maltidstyp + plan-atgarder

Veckoplanen fyller nu ALLA slots (stegvis fallback, inga tomma dagar),
undviker tva soppor/samma kok i rad och styr soppor mot lunch (inte
middag). Default lunch+middag varje dag. Plan-atgarder: 'Jag lagade
detta' bara ratt dag; 'Hoppa over' ersatt med 'Ta bort' (ny DELETE
/v1/week-plans/:id/entries/:entryId). Verifierat mot 393 recept:
14/14 slots fyllda, 0 upprepningar, 0 soppor pa middag.
