refactor: reduce DOM nesting and simplify templates

- Remove nested .wrapper div in recipe page using CSS Grid with full-bleed background
- Consolidate multiplier forms in IngredientsPage into single form
- Simplify fermentation conditionals in InstructionsPage with optional chaining
- Use conditional rendering instead of visibility wrapper in Search
- Remove unnecessary dialog wrapper in TitleImgParallax
