Changed from bind:value to oninput handler to properly support
form submission. The Input component doesn't support two-way
binding, so we need to use the oninput callback pattern.

Issues fixed:
- Section header elements were cramped on one line

- Text was getting truncated

Changes:
- Add flex-wrap to .section-header to allow wrapping
- Add flex-wrap to .section-title-row for responsive layout
- Add flex-wrap to .filter-toggles for better mobile support
- Add white-space: nowrap to .game-count to prevent mid-text breaks
- Add gap spacing to section-header for consistent spacing

Now the layout gracefully wraps when space is limited, preventing
awkward text breaking and maintaining readability.

Header:
- Replace custom cloud card styling with Card component (variant="large")
- Remove duplicate CSS for cloud effects
- Keep only header-specific positioning and layout styles

Footer:
- Replace custom buttons with Button components (secondary, primary)

During migration to on-protocol, many active games lack complete
Constellation data and are misclassified as 'waiting'. Using loose
filter (status != completed) until migration is complete.

TODO: Revert to strict filter (status === active) after migration.

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Changed filter from 'status != completed' to 'status === active'.
This prevents games waiting for players from appearing in Current Games.

flexbox gap and making game-info flex: 1
