feat: render full map content (image, intro, markers) in PagedJS

- Fix template check 'carte' → 'map' so map subpages are served by API
- Add parseMarker() and enrich parseCarte() with static image, intro, markers
- Include map children in parseGeoformat() alongside chapters
- Resolve map block references in chapters to full carte data
- Update narrative store flattening with new carte fields
- Replace MapBlock placeholder with full carte rendering (title, image, tags, intro, markers with icons and blocks)
- Add default marker-pin.svg for markers without custom icon
