Migrate route param gating to `dataCollection.userInfo`

[antonis]

Replace sendDefaultPii check in React Navigation integration with dataCollection.userInfo.

Callsite

• reactnavigation.ts:488 — dynamic route params (e.g. [id], [...slug]) are only attached to navigation spans when sendDefaultPii is true

Should read from resolved dataCollection.userInfo instead.
