claude code agent 227 99359fa0fa fix(editor): load the float responsive rule + test applyAlignment (#145 review)

Review of #157 (Request changes) caught two blockers:

1. DEAD responsive CSS: the `@media (max-width:600px)` float-reset was added to
   `image-resize.module.css`, which is imported NOWHERE — the image container's
   classes come from `common/node-resize.module.css` (via buildResizeClasses).
   So on mobile a floated image kept its px width + float and crushed the text,
   exactly the failure the rule promised to prevent. Moved the rule to
   `common/node-resize.module.css` (the module actually imported by the resize
   node views); its `:global([data-image-align=...])` selectors are data-attr
   based, so they work unchanged. Reverted the dead addition from the (pre-existing,
   orphaned) image-resize.module.css.

2. `applyAlignment` was untested. Exported it and added `image.spec.ts` (vitest/
   jsdom) covering all five align values, the data-image-align mirror, and the
   floatLeft -> left reset-then-apply (the guard against a leaked float).
   Switched the float writes to the canonical CSSOM `cssFloat` property (portable:
   browsers + jsdom; behavior identical to the `.float` alias).

editor-ext build + client tsc clean; 6 image.spec tests green.
