upgrade: adopt V8.12.0-dev.1 (V8.11 unified professional UI + V8.12 workflow usability)

- Overlay 26 changed files from SiteForge_Enterprise_V8_12 (UI layer only:
  professional-ui.js/css, workspace/factory-v2/operations/editor templates,
  +2 test files, compose/ci/scripts/docs)
- Re-apply v8_workflows type-mapping fix (类型/分类) lost in upgrade
- Pin compose project name to siteforge-v8-10 so existing data volumes
  (hesupipe site 483295c29ea0, 193 entries) keep attached
- Drop stray .s10_* state files; ignore .s10_*/.sf_*/.s87_* patterns
- Plan/spec revisions per plan-review round 1 (icons are new design,
  real test assertions, recorded deviations)

Tests: 226 passed / 1 env-only failure (test needs node binary in PATH,
absent in python:3.12-slim container; host node v24 --check all 9 JS OK)
