Pass activeAnnotationId to TranscriptionEditView. An $effect watches
it and sets activeBlockId to the block matching the annotation,
activating its turquoise focus border.
2 new tests (RED/GREEN):
- activates block matching activeAnnotationId (turquoise border)
- no block activated when activeAnnotationId is null

HTML5 drag-and-drop didn't work — the grip handle couldn't initiate
drag properly. Replace with pointer event-based drag:
- Grip handle pointerdown starts drag, captures pointer
- Pointermove tracks offset, shows floaty style (shadow, scale, ring)
- Turquoise drop indicator line appears between blocks at cursor position
- Pointerup finalizes: reorders array and calls PUT /reorder endpoint
Visual feedback:
- Dragged block: shadow-xl, ring-2 ring-turquoise/40, scale 1.02, opacity 0.9
- Drop indicator: turquoise h-1 rounded bar between blocks
6 new TranscriptionEditView tests:
- renders blocks in sort order
- shows next-block CTA
- shows empty state
- move-up disabled on first block
- move-down disabled on last block
- drag handle present on each block
