feat: send gen params to workflow with visual cues

- Add genParamsMapper.js: sampler/scheduler display→internal mapping,
  combined-name parsing, widget matching
- Add sendGenParamsToWorkflow() in uiHelpers.js: resolves sampler,
  fetches registry by send_gen_params marker, sends via update-node-widget
- Add send-params-btn UI in showcase hover panel and recipe modal
- Add flashWidget() in workflow_registry.js: text-color visual cue
  on updated widget values (Vue: inline style + CSS, canvas: property shadow)
- Add silent option to sendWidgetValueToNodes for consolidated toast
- Normalize param display labels (cfg_scale→CFG, etc.) in recipe modal
- Add 33 tests for genParamsMapper; update existing test assertions
