deterministic + unique ids in 6 components (node-derived scope)

Migrates Menu, ColumnLayout, Countdown, Gallery, Tabs, InputField, and
TextareaField from Math.random()/content-hash scope ids to the threaded
Craft node id (via scopeId()), keeping every emitted element id,
aria-controls/aria-labelledby/for, and inline <script> function
name/getElementById() call consistently scoped per component.

Resolves the two Important id-collision review findings:
- Tabs: tabId was djb2(anchorId||labels) -- two default Tabs instances
  produced identical aria-controls/aria-labelledby ids, so one instance's
  arrow-key script clobbered the other's tab/panel wiring.
- InputField/TextareaField: fieldId was `field-${name}` -- two fields
  sharing a (often default) name produced duplicate <label for>/<input
  id> pairs, breaking the for/id association for one of them.

Also eliminates the remaining Math.random() scope ids in Menu (hover CSS
class scope) and ColumnLayout (nth-child width CSS class scope), so no
export component is non-deterministic anymore.

All fall back to a stable content hash (never Math.random) for legacy
2-arg toHtml() call sites without a node id.
