feat(jobs): Phase 6 — Tablet Station for fp.job

Operator-facing touchscreen UI. Three modes:
- job_picker: list of active jobs as big touch cards
- job_detail: job header + steps list, click a step to view detail
- step_detail: big Start/Finish buttons depending on state

Backend: 4 JSON-RPC endpoints under /fp/jobs/tablet/* for jobs
list, job detail, start step, finish step. Calls through to
fp.job.step.button_start / button_finish so all the audit
preservation, timelog creation, duration_actual roll-up logic
from Phase 1 still applies.

Menu entry 'Tablet Station (Native)' at sequence 3 (top) of the
Plating Jobs (Native) submenu inside the existing Plating app.

Manifest 19.0.2.3.0 → 19.0.2.4.0.

Part of: native job model migration (spec 2026-04-25)
