fix(home): wrap map init in DOMContentLoaded to fix broken homepage map

After the CDN elimination refactor, maplibregl moved from an inline head
script to the bottom-group bundle — but home.html.twig still called
new maplibregl.Map() immediately, before map.js had loaded. Wraps both
the active-trip and between-trips script blocks in DOMContentLoaded,
matching the pattern already used in trip/map/feed-map templates.
