Refactor report pipeline: redesign HTML, add motion alignment, remove legacy reporter

- scripts/generate_cutter_report.py: complete HTML redesign with glassmorphism
  dark-mode style, compare video links in markdown output
- cli.py: cmd_report now calls _regenerate_cutter_report directly; also writes
  legacy match_report.html; removes dependency on src/pipeline/reporter.py
- src/cv/global_scan.py: add motion-phase alignment refinement step after
  initial in-point search (align_in_point_by_motion, threshold +0.015)
- Remove HANDOVER.md and src/pipeline/reporter.py (superseded)
