fix(chrome): replace 2 platform emoji + 1 en-dash with on-brand tokens

PRODUCT.md anti-references call out the SaaS-template / emoji-in-chrome
register: the reference products (Linear, Stripe, Things 3) don't put
platform emoji in product chrome. Three small drift spots:

- Balance saved-cards link used a 💳 emoji as the leading icon.
  Replaced with a new CreditCardIcon added to the barrel (Heroicons-
  style stroke, matches the chevron / chat / wallet siblings).

- Subscription paused-info banner used a ⏸️ emoji. Replaced with a
  new PauseIcon added to the barrel. Same 24×24 stroke, currentColor,
  preserves the urgent-400 tint via inline style.

- Balance payment-method min/max range used a literal en-dash ('–')
  in source. PRODUCT.md's anti-em-dash rule covers the en-dash by
  the same logic. Switched to a translated 'to' connector
  (t('common.rangeTo', 'to')) so other locales can translate freely.
