Backend /api/graph now returns ALL non-trashed notes as nodes, each with its
first label's color; edges unchanged. GraphView reworked: drag a node to
reposition it (pins to cursor + reheats the sim), pan the background, wheel-
zoom toward the cursor, a "Show unlinked notes" toggle (connected-only by
default), a Reset view button, and nodes filled by label color. Click (a
press without a drag) still opens the note; re-fetches on view open.

Give labels a color (migration 0011 adds labels.color, server_default
'default' so existing labels keep the neutral chip). The PATCH endpoint now
updates name and/or color; note serialization carries each label's color.
Frontend: a swatch picker per label in the Edit-labels modal, colored chips
on cards + in the editor (LABEL_CHIP_CLASSES), and a color dot on each
sidebar label. Reuses the note color vocabulary. (Graph node coloring rides
this in the graph-liveliness task.)
