Unify graph docking, fix device hot-switch, and compact UI cards

- Unify minimap/toolbar/legend drag+dock into shared _makeDraggable() helper
- Persist legend visibility and position, add active state to toggle buttons
- Show custom colors only on graph cards (entity defaults remain in legend)
- Replace emoji overlay buttons with SVG path icons
- Fix stale is_running blocking target start (auto-clear if task is done)
- Resolve device/target IDs to names in conflict error messages
- Hot-switch LED device on running target via async stop-swap-start cycle
- Compact automation dashboard cards and fix time_of_day localization
- Inline CSS source pill on target cards to save vertical space
