fix(routing): fix capture amount and add retries for 3DS cold-start
- Routing/Stripe.js Capture config expected amount 6000 but PaymentIntent
creates with 1100; align response assertion to 1100
- Add retries (runMode: 3) to handle-three-ds-redirection in context 1
only — contexts 2/3/4 pass the identical step; context 1 is first in
the suite and can hit Stripe sandbox cold-start iframe latency
