Tree layout toggles (landscape/portrait/fan), card->profile, server search

Tree page gets Landscape/Portrait/Fan toggles: landscape & portrait via family-chart's orientation; a hand-rolled radial Fan chart of ancestors (rings per generation, click to recenter). Clicking a card recenters and updates an 'Open <name> →' link to that person's profile. The People directory search now hits the server-side pg_trgm fuzzy endpoint (debounced) so it spans the whole tree, not just the loaded page.
