Subject: Phase 1: standalone events, external_url on nodes

- Migration: node_id nullable on events and occurrences, add
  title/description/is_primary to events, external_url to nodes
- Existing events marked is_primary: true (were all 1:1 with nodes)
- Node: has_one :event -> has_many :events
- Event: belongs_to :node optional, validates title presence for
  standalone events, is_primary uniqueness scoped to node_id,
  display_title helper falling back through node title
- Occurrence: belongs_to :node optional, summary falls back to
  event.display_title
- nodes_helper: event_information uses events.first (interim; will
  be replaced in Phase 3 event UI)
- Tests: fix node.event -> node.events.first in event_test
