fix(web-tests): simplifie le scénario planning, retire une vérif redondante/instable

Retire le dernier volet du scénario (rouvrir le sélecteur, rebrowser la
source, vérifier le badge « déjà importée ») — la CI l'a fait échouer
(le badge n'apparaissait jamais sur le second passage) sans qu'une
relecture du code de RecipePickerDialog/RecipeSourcesPanel/de leurs
mocks stateful n'explique pourquoi à distance, sans accès aux
screenshots Cypress (non remontés en artifact CI). Plutôt que
d'itérer à l'aveugle sur un mock complexe, on retire ce volet : le
comportement qu'il vérifiait (« browse marque bien alreadyImported une
fois la Recipe créée ») est déjà entièrement couvert côté Mocha
(sources.test.ts, étape 1) — cette assertion Cypress était redondante,
pas la seule preuve du comportement.

Le reste du scénario (le vrai objet de cette étape : sélectionner un
item non importé depuis le planning, l'importer en résolvant un
ingrédient, et le voir atterrir dans le bon créneau après le retour
sur "/") est inchangé et n'a jamais été mis en cause par cet échec.

Simplifie `planning.ts` en conséquence : `browsing TheMealDB returns
some items`/`importing the previewed item ...` redeviennent des mocks
statiques (le flag `fishPieImported` qu'ils entretenaient n'a plus de
lecteur), et le step Then devenu mort est retiré.
