feat(analytics): add custom event tracking to NutriPhi and ManaDeck

Add NutriPhiEvents (mealAdded, mealDeleted, photoAnalyzed, textAnalyzed,
goalsUpdated, favoriteSaved, favoriteUsed) to shared analytics utils.
Add deckDeleted and cardDeleted to ManaDeckEvents. Wire up event calls
in NutriPhi meals store and ManaDeck deck/card stores.
