1.0.4: Smarter auto-assign, quick dish entry, calendar fix, frictionless onboarding

- AutocompleteEngine: no-repeat rule now applies to all dishes (not just tagless ones); fallback still allows repeats when no alternative exists
- CalendarService: update existing events instead of delete+create to prevent duplicates; fix weekStartDate using plan date instead of currentWeekStart
- DishFormView: form stays open after saving in create mode for quick multi-dish entry; Done button to close; saved feedback banner
- OnboardingViewModel/FirstDishesStepView: dishes are now optional during onboarding; Finish button always enabled
- AnalyticsService: new events — onboarding_step_viewed(step) and auto_assign_used(filled, unfilled)
- Localization: dish_done and first_dishes_optional_hint added in 6 languages; release notes updated in all 6 languages
- Version bump: 1.0.3 → 1.0.4 (build 19)
