feat(planner): align tile design with spec

Front face:
- Full dual gradient overlay (dark top 32% → transparent → dark bottom 55%)
- Day abbreviation + date number pill at top of each tile
- Recipe name 13px/weight-300 with text-shadow
- Meta line (cookTimeMin · effort) below name
- Glassmorphism tag pills (protein + cuisine only)
- State rings via box-shadow (yellow for today, green for selected)
- Dimming (opacity 0.42) on non-selected filled tiles

Back face:
- Koch-Modus as green primary button
- Entfernen as red outline (transparent bg)
- All buttons 11px / weight 500

EmptyDayTile: add day header + spec-aligned suggestion list layout
Page: remove external column header (now rendered inside each tile)
