💄 Console UI polish round

Merge the load form and files tree into one "Load graph from Penpot" box (tree first, uuid + Load/Unload in a row); Loaded session carries HH:MM in its legend; the Live changes box stays hidden until the first change arrives; query fieldset reads "Query graph (LadybugDB Cypher)" with the link covering both terms. Drop the hover tooltips (distracting, useless zoomed out) and the resident-size estimate (per-table counts stay on hover); every toggle gets a "When set/checked ..." title. Depth fold: 0 now expands every container (no more hunting for max depth). Node inspector: two-column flow, structured or long values folded behind the file-tree disclosure triangle.
