Implement time-based week view with scrollable 24-hour layout

- Add comprehensive time grid structure with hourly and half-hourly divisions
- Implement scrollable week view with sticky header and time labels
- Create 25 time labels (12 AM through 11 PM plus boundary) with proper formatting
- Add 25 matching time slot backgrounds for visual alignment
- Style time labels with appropriate sizing and boundary indicators
- Position events absolutely over time grid (basic positioning for now)
- Set proper container heights and scrollable content area

Note: Time slot alignment still needs refinement for complete 24-hour coverage
