feat(billing): unified BillingCardComponent + annual toggle disabled state (#4149)

* fix(billing): align devkit static-content with V4 plan schema + close card edge cases

Phase 0 critical-review BLOCK findings — iter 1:

- [critical] Migrate devkit static-content plans to V4 schema (title/subtitle/highlight)
  to match the new BillingCardComponent contract. Drop legacy
  name/tagline/highlighted + featureSections + included:false features +
  equivalences. Cards now render with proper titles and elevated variant for the
  highlighted plan on the devkit dev server.
- [high] BillingCardComponent: skip cta-click emit when cta.to is set. v-btn's
  :to binds router-link which navigates natively; emitting also triggered a
  duplicate $router.push in the parent's @cta-click handler with a divergent
  URL (free+guest plan dropped the redirect query param).
- [medium] Drop dead _equivalences computation in resolvedPlanItems — the new
  BillingCardComponent does not consume equivalences. Trawl downstream already
  removed them too.
- [low] Drop dead maxAnnualSavingsPct prop on BillingPricingToggleComponent —
  caption was removed in V4 (savings live on card price.chip). Also drop the
  prop binding in billing.pricing.view.vue.
- Test updates: add cta.to → no-emit test; drop maxAnnualSavingsPct usage in
  toggle tests (prop removed); simplify i18n mock (savingsActive key unused).

All tests green (1669/1669, 101 files). Lint clean.

* fix(billing): preserve signup redirect query + drop dead view code

Phase 0 critical-review BLOCK findings — iter 2:

- [high] Free+guest CTA `cta.to` was '/signup' (string), losing the redirect=/pricing
  query param. Card skips emit when cta.to is set (intentional double-nav fix), so
  the view's onCtaClick fallback that pushed /signup?redirect=/pricing was dead.
  Fix: pass cta.to as { path: '/signup', query: { redirect: '/pricing' } } — v-btn :to
  accepts the same shape as $router.push().
- [medium] Drop dead `meterMode` computed from the view (only consumed by the
  removed _equivalences logic).
- [low] Update billing.pricing.view.unit.tests.js mock fixtures to V4 schema
  (title/subtitle/highlight) — masked schema-compliance gaps.
- [low] Clarify BillingCardComponent ITEM SCHEMA doc: cta is a string in
  static-content plans but expanded into an object by resolvedPlanItems; cta-click
  emit guard now documented (disabled OR to=set).

Note: usePricing.maxAnnualSavingsPct stays — it's a public composable API still
tested by billing.usePricing.unit.tests.js. Downstream may consume it.

All tests green (1669/1669). Lint clean.

* chore(billing): drop inert density attr on pricing toggle (no-op prop)

Phase 0 nit — BillingPricingToggleComponent has no density prop; the binding
falls through as inert HTML attribute on the root div with no effect.
Remove the binding (Vuetify density is not surfaced by this wrapper).

* fix(billing): use template literal for priceChip text (no i18n dep in tests)

Replace this.$t('billing.pricingCard.saveAnnual') with Save ${pct}% template literal
to match master convention and avoid $t not a function failures in unit tests.

* fix(auth): signup honors $route.query.redirect like signin does

Addresses Copilot review on #4149. The pricing CTA already set
?redirect=/pricing on /signup (Phase 0 fix cc6c585), but signup.view
silently dropped it — only signin.view:157 honored redirect. The
redirect param was therefore dead code from the signup CTA's POV.

Adds a pushAfterAuth() helper mirroring signin's pattern:
- typeof redirect === 'string' && redirect.startsWith('/') → push redirect
- otherwise → push config.sign.route
- typeof guard prevents arrays (?redirect=/a&redirect=/b); startsWith('/')
  guard prevents open-redirect to external URLs.

5 call sites swapped to pushAfterAuth():
- watch.auth (orgs disabled branch)
- created() (already logged in + has org)
- validate() success, orgs enabled, no setup needed
- validate() success, orgs disabled
- proceedToApp() (end of org flow)

4 new unit tests (redirect honored / fallback / open-redirect guarded /
proceedToApp redirect). Total signup tests 25 → 29.
