feat(canvas): reimagine ProcessGraph as FM industrial blueprint

Pulls the actual FM06/flow-master-design-philosophy doctrine
(DESIGN_PHILOSOPHY.md + SYNTHESIS.md + IMPLEMENTATION_STANDARD.md
+ ADR 0001/0002) and rebuilds the canvas to match: 'operations
cockpit', 'industrial, instrumented, accountable'. Light paper
canvas + navy frame + amber accent + 1px rules + square edges +
monospace operational labels.

WHAT CHANGED
- ProcessGraph.tsx rewritten: square 1px navy nodes, mono uppercase
  labels, orthogonal step edges (ReactFlow type:'step' → MLHV only),
  two-layer Background (8px minor + 64px major navy hairline grid),
  doctrinal palette tokens via var(--bp-*).
- BlueprintFrame.tsx (new): top instrument readout strip
  (DEF / VERSION / HUB / NODES / EDGES / SRC / MODE / TX), top + left
  rulers with 8/64px ticks, navy corner glyph at origin, bottom
  status legend.
- index.css: scoped [data-canvas="blueprint"] block (~280 lines)
  declaring 11 doctrinal hex tokens once; opacity derivatives go
  through CSS color-mix(in srgb, var(--bp-navy) 13%, transparent)
  not raw rgba(). No box-shadow on selected node (outline instead).
- LeftRail.tsx: gate toast now names the real endpoint
  (POST /api/runtime/transactions/{id}/actions/{submit,save_draft})
  on the unsigned-in path too, restoring the convention from the
  prior real-mutations pass.
- qa/smoke.mjs updated for the new selectors (.bp-node,
  .bp-readout-blueprint). Old guided-tour assertions replaced with
  Studio scene assertions. 27/27 PASS.
- qa/smoke_blueprint.mjs (new): 15 assertions covering S1–S3 + S5.
- qa/palette_audit.mjs (new): three checks — doctrinal CSS hex,
  no raw rgba() in blueprint scope, no hardcoded color literals in
  blueprint TSX. All pass.

ORACLE-REVIEWED
Round 1 FAIL: hardcoded TSX color literals + box-shadow + rgba +
narrow palette audit. Round 2 PASS after fixing all four.

CONTRACT EVIDENCE
- vitest: 5 files, 24 tests, all green
- main smoke: 27/27, 0 console errors
- blueprint smoke: 15/15, 0 console errors
- palette audit: 11 CSS doctrinal hex tokens, 0 raw rgba, 2 TSX files clean
- vite build: green

Confidence: high
Scope-risk: narrow (scoped [data-canvas="blueprint"])
Not-tested: pixel-level visual diff (Oracle could not inspect images
this round; relied on programmatic DOM + path-command assertions)
