feat(resources): one tabbed page per resource

In the resource-first model a resource is the unit of capacity, so its
working hours, holidays, services, skills and categories belong to it — not
scattered across a list page's modals plus a separate calendar page.

/admin/resources/{uuid} now carries six tabs and the active tab lives in the
query string, so back and refresh land on the same view. The old
/calendar URL redirects to ?tab=hours instead of 404ing.

The skills and services modal bodies became panels the tab renders directly;
the modals are now thin wrappers, so the list page keeps working unchanged
and there is still one implementation of each editor.
