fix(layout): remove constraining height and overflow from demo containers

SUMMARY:
Removed min-h-[600px] and overflow-auto that were causing content display
issues. Simplified to just w-full on inner containers.

ISSUE:
The min-height and overflow-auto combination was preventing proper content
rendering, causing the 'Simulate Pressure Increase' button to be hidden.

FIX:
- Removed min-h-[600px] from parent containers
- Removed overflow-auto from parent containers
- Added w-full to #pressure-chart and #activity-timeline divs
- Allows natural content flow and proper button visibility
