refactor(ssr): shared component partials own their CSS classes

Bake the Tailwind class base into the shared Selmer component partials so the
partials own their markup and callers pass only data + a small variant
(width / size / color). Applies across all four modals that share them
(bulk-code, invoices, sales-summaries, transaction-edit).

- typeahead / select / location-select / money-input / validated-field /
  button / a-button / a-icon-button: the class base, the validated-field
  has-error toggle, and the button color ladders now live in the .html. The
  sc/*-ctx fns pass width / variant / extra / color plus the non-class attrs
  (computed exactly as before, so every non-class attribute is unchanged).
- bulk-code templates updated to the new partial contracts; account-row pulls
  money-input and a-icon-button in via includes.

Verified: every component's class SET is identical to before across all
variants (14/14 oracle match -- buttons reorder/dedupe classes, CSS is
order-independent); bulk-code full render is DOM-equivalent to the pre-sweep
baseline (class-set + attr-order normalized) for empty / populated / error;
browser QA of bulk-code (full flow) and transaction-edit (open + render) clean,
no JS errors; invoices + sales-summaries compile and render through the same
sc/* fns.
