Fix map tooltips, journey creation, and contributor avatars

- Map tooltips now respect light/dark mode via CSS variables
- Journey creation inherits cover image from first selected trip
- Only day-assigned places are synced to journey (no unplanned places)
- Place count in trip picker reflects assigned places only
- Contributor avatars shown in journey detail page
- Suggestion banner button visible in dark mode (!important override)
- Dashboard list view uses correct trips array and status label
