Add after_route_name to boss battle export/seed pipeline

Exports now include after_route_name (resolved from the route FK),
and the seed loader resolves it back to an ID on import. Also adds
a draft bean for displaying encounter-less locations.

+title: Display encounter-less locations for egg hatching
+status: draft
+type: feature
+created_at: 2026-02-08T14:49:50Z
+updated_at: 2026-02-08T14:49:50Z
+---
+
+Some routes/locations don't have wild encounters but are still relevant for gameplay — particularly for hatching eggs. Currently these locations are hidden or not useful in the run view since they have no encounters to log.
+
+Add support for displaying locations that have no encounters in the run view, so players can track egg hatches or other location-based events there.
+
+## Checklist
+
+- [ ] Determine how encounter-less routes should appear in the run view (e.g. different visual treatment, no encounter status dot)
+- [ ] Update route filtering logic to include routes without encounters when relevant
+- [ ] Add ability to log an egg hatch at a location (new encounter type or dedicated UI)
+- [ ] Consider whether these locations need an admin-side flag (e.g. `show_without_encounters`) or if all routes should always be visible
