Add person-detail page with events timeline and relationships

New /trees/[id]/persons/[personId] view: life-events timeline with add/remove, and relationships grouped into parents/children/partners/siblings with an add form (kind + person picker + qualifier). People in the tree list now link here. Regenerated the OpenAPI client for the new endpoints.
