Adds the public viewing surface in the UI — shareable, no-login pages backed by
the redaction-safe /api/v1/public API:
- /p/[treeId]: tree name + searchable people directory (living people show as
"Living person"; counts; links to person pages).
- /p/[treeId]/persons/[personId]: person detail — events, alternate names, and
parents/partners/children as links to other public person pages.
- app/p/layout.tsx: slim public header (logo + Sign in), no app sidebar.
- robots.ts: allow /p/, disallow the authenticated app sections.
- Trees list: a "Public page ↗" link on every non-private tree so the owner can
grab the shareable URL.
Client-rendered (same-origin fetch via Caddy). Follow-up (needs a frontend
SSR→backend base URL + a compose/env deploy step, so not auto-applied by
Watchtower): true server-rendering for SEO, a dynamic sitemap of public trees,
and per-page noindex for unlisted/site_members.
tsc clean; next build passes (both routes dynamic).
