fix(jobs): make "In Progress" workflow milestone fire reliably

Two coupled fixes so the workflow bar shows "In Progress" when work
is actually underway, even on recipes without kind tagging:

  B. Auto-promote fp.job.state on first step start.
     fp.job.step.write hook detects step transitions to in_progress
     and promotes parent job state from 'confirmed' → 'in_progress'.
     Without this, fp.job.state never reached 'in_progress' anywhere
     in the codebase, so the trigger_on_job_state='in_progress'
     path was dead code.

  C. Smarter trigger_first_step_started for untagged recipes.
     For tagged recipes (any step has kind in wet/bake/mask/rack),
     keep the strict kind-based check. For untagged recipes (all
     steps kind='other' or similar), fall back to "any step in
     in_progress/paused/done" so the milestone fires regardless of
     recipe authoring quality.

Verified end-to-end on entech with untagged steps:
  - confirmed → in_progress when first step starts
  - workflow bar tracks at in_progress through the work
  - workflow bar advances to done when all steps done/skipped

Recipe authoring still encouraged for full Received / Inspected
intermediate states (those keep their default_kind triggers).
