feat(jobs+shopfloor): live-step priority chain + done-job filter

Fix the Shop Floor plant kanban so cards land in the right column:
- fp.job._compute_active_step_id walks priority chain
  (in_progress > paused > ready > pending), not just in_progress
- fp.job._compute_card_state edge case respects job.state='done'
  (no more bogus 'contract_review' label on done jobs)
- fp.job.step._compute_area_kind reads kind.area_kind directly;
  legacy _STEP_KIND_TO_AREA dict removed (50+ lines deleted)
- /fp/landing/plant_kanban filters out done/cancelled jobs from
  the live board

Migration 19.0.10.25.0 backfills template metadata (codes,
descriptions, icons, kind_id) on 30 unfinished library templates
and repoints recipe nodes for 6 unambiguous name patterns
(Blasting -> blast, Ready For X -> gating, De-Masking -> demask,
Scheduling -> gating, Nickel Strip -> wet_process,
Pre-Meas/Check Sulfamate -> inspect).

Battle test bt_s24_between_steps.py covers between-step routing,
paused step lifecycle, and done-job board filter.
