[web] Add pro-value-framing split test copy (#36628)

* feat(web): add pro-value-framing split test copy

Serve quantified, benefit-led plan differentiators on the plans and
interstitial pages to the `enabled` variant of the `pro-value-framing`
split test, in place of the vague "increased/max AI allowance" and
"10/unlimited collaborators" framing.

The variant changes the bullet set and order as well as the strings, so
it swaps in its own short feature list rather than remapping keys: Pro
leads with "Everything in Standard, plus:", Free gains Error Assist and
"Compile simple projects". The plans page comparison table mirrors the
card wording in its AI allowance row.

* test(web): assert plan copy numbers against plan features

Check the quantified claims in the plan copy against the SaaS plan
features: the collaborator limits, and the "24x" compile timeout claims
as the ratio of the paid to the free compileTimeout. The "2x more AI
usage" claim is checked against the allowance tooltips, since the
allowances themselves come from AI_*_QUOTA_GRANT and are not available
in the unit test environment.
