ui: editor-like QoL — selection highlight, drag feedback, keyboard nav

Selection / highlight:
- .vv-row-selected: blue tint + left accent bar (was barely-visible gray)
- .vv-sb-selected: same treatment, consistent across both panels
- .vv-df-active (containers): match new selection style
- .vv-job-row + .vv-sb-row: smooth transition on state changes
- .vv-orch-row: hover feedback + pointer cursor (was no visual response)

Drag and drop:
- .vv-drag-ghost: adds dashed ring so source item stays visible while dragging
- .vv-drop-line: blue glow to match selection accent (was flat green)
- All drop targets: unified blue theme (.vv-children, .vv-folder-children)
- .vv-library-zone drop target: improved red with inset glow
- .vv-drag-handle:active: grabbing cursor state
- document.body.vv-is-dragging: cursor:grabbing on entire page during drag
  (added to all three drag start handlers + failsafe document dragend)

Keyboard navigation (scheduler):
- ↑/↓: navigate between top-level orchestrator cards
- Home/End: jump to first/last card
- Escape: close right panel, return to suggestions
- /: focus log search when log panel is open
- All shortcuts suppressed when focus is in any input/textarea/select
