[web] Remove redundant monthlyTimesTwelve from pricing tables (#35506)

* [web] Remove redundant monthlyTimesTwelve from pricing tables

monthlyTimesTwelve was always exactly monthly * 12 in every pricing row,
and the value was only ever used to render the "billed monthly for a year"
strikethrough price in the compile-timeout paywall.

- Drop the stored field from the pricing tables
- Send raw monthly/annual numbers in ol-standardPlanPricing instead of
  pre-formatted strings
- Format the prices (and derive the strikethrough as monthly * 12) in the
  paywall modal via the frontend currency helper

No user-facing change: the displayed prices are identical.
