feat(jobs,shopfloor): smart buttons + QR scanner + NFC tank pages

Three connected operator-workflow features for entech.

A. fp.job smart buttons — count fields and action methods for sale
   order, steps, deliveries, invoices, payments, quality holds,
   certificates, time logs, and portal job. Each is an oe_stat_button
   that drills into the matching records, mirroring the sale.order
   pattern. Cross-module models are runtime-detected so the form
   stays clean when bridge modules are uninstalled.

B. Reusable QR scanner OWL component (`<QrScanner/>`) wired into the
   Manager Desk, Tablet Station, Plant Overview, and Process Tree
   headers. Click → modal with rear-camera stream (getUserMedia) +
   BarcodeDetector live decode → opens the matching fp.job form via
   the action service. Falls back to a manual URL paste box on
   browsers without BarcodeDetector. Works on iOS 17+ Safari and
   Android Chrome. Width uses `min(420px, 92vw)` wrapped in #{} so
   dart-sass passes it through verbatim instead of trying to compute
   incompatible units at compile time.

C. /fp/tank/<id> public-but-auth-required tank status page for NFC
   taps. Renders the tank's current step (in-progress / paused),
   queued ready steps, and most recent bath chemistry log (lines
   table) on a mobile-first page. URL-based so it works on iOS Safari
   without the Web NFC API — the operator taps the NFC tag, the URL
   opens in the default browser, the page auto-renders. New
   web.assets_frontend bundle entry pulls in the design tokens +
   tank_status.scss.

Manifest version bumps: jobs 19.0.5.0.0, shopfloor 19.0.16.0.0.
Tests: 44 pass (3 new smart-button assertions added).
