feat(project-form): wire the rich data form (labels-left) + edit tabs

The edit/create project page used a stripped-down inline form. Rewired it
to the existing-but-orphaned pieces:
- Project Data uses the rich partial project-data-form (labels-left/field-right
  layout, sections Identification/Location/Planning, address search + Leaflet
  map with draggable marker + reverse/forward geocoding, country dropdown)
- When editing, tabs added for Phases / Users / Companies (nested Livewire
  components phase-list / project-users / project-companies)
- ProjectForm now provides $countryList (the partial's country dropdown needs it)
- Added the map JS the partial was missing: inits #project-location-map, search
  box, and calls $this->setLocation(lat,lng,address,country) so the wire:model
  fields update
