feat: scaffold PulseNode dashboard (M1)

Next.js 16 + TypeScript + Tailwind v4 app with a YAML-driven config system: schema validation (zod), .env interpolation, and a widget registry rendering bookmark/search/group widgets. CSS custom properties (--pn-*) drive theming and are overridable from config.yml's theme.variables. Config load errors surface as a readable error page instead of crashing the app. Hot reload, docker/system/http collectors, and the WebSocket push layer land in later milestones per the approved plan.
