fix(#75): IMP-47A mdx03 frontend execution stabilization (u1~u4)
u1: SlideCanvas iframe sandbox += allow-scripts (allow-same-origin preserved)
→ embedded-mode script in slide_base.html now applies html.embedded
→ standalone CSS reset deactivates inside iframe; no clipping
u2: designAgentApi.loadRun merges candidate_evidence + v4_all_judgments
+ v4_candidates via Map<template_id|id|frame_id> dedup,
LABEL_PRIORITY (use_as_is<light_edit<restructure<reject) then
confidence desc, capped TOP_N_FRAMES=6
u3: Home.handleGenerate useCallback deps = [uploadedFile, slidePlan,
userSelection, pendingZones, pendingLayout] (5-tuple, stale-closure fix)
u4: tests/manual/imp47a_e2e.md — mdx03 manual e2e spec (5 axes)
Frontend-only. Backend src/ untouched. No template/catalog edits.
Determinism preserved (no LLM in frontend merge logic).
Baseline: pytest -q tests → 623 passed.
