Add Dashboards UI: PromQL-backed bar/line/pie panels saved per profile (ticket 014)
Backend: replace Profile.dashboards' opaque JSON stub with typed Dashboard/Panel structs, add ProfileStore CRUD (create/save/list/delete dashboard) and matching /api/settings/profiles/:name/dashboards[/:id] routes, with tests covering the HTTP round trip and persistence across a simulated restart. Frontend: add recharts (lightweight, React 19-compatible) and a Dashboards component with a dashboard builder (create dashboards, add/remove/edit panels with a PromQL query + chart type), live per-panel previews that respect the active time range and show malformed-query errors inline instead of crashing, and load/save wired to the new profile-backed persistence.
