feat(planner): overhaul desktop layout — flip tiles, no right panel

Replaces 3-panel layout with 2-panel (sidebar + full-width grid):
- Remove persistent right panel and toolbar + Gericht hinzufügen button
- grid-cols-7 tiles use DesktopDayTile (CSS 3D card flip)
- RecipePickerDrawer slides in on tile CTA / Gericht tauschen
- Page-owned activeSlotId + drawerOpen/drawerSlotId state
- Single Escape handler: drawer > flip priority
- Extend server load to forward recipe tags from /v1/recipes API
