docs: sharpen agentcard copy on the payments overview

[keyserfaty]

hi! karen from agentcard here. a few copy corrections on the agentcard side of the payments overview so it matches how the integration actually behaves for end users.

what changed

• provider card: agentcard adds users' cards to agentcard's vault; the user approves each transaction with Face ID and earns points on the purchase.
• payment-method collection: the enrollment page is fully white-labeled, not a generic hosted action.
• purchase authorization: the user approves with Face ID.
• payment handoff: agentcard executes the request and returns the response.
• reuse: cards can be reused for recurring and one-time purchases.
• two new comparison rows: card points, and chargebacks (users can dispute transactions from their online banking).

nothing outside the agentcard column changed. happy to adjust wording if it doesn't fit your voice.

Overview
Updates the payments overview so Agentcard is described the way the product works for end users, without changing Stripe Link column content.

The Agentcard provider card now mentions vault enrollment, Face ID per-transaction approval, and points on purchases. The comparison table’s Agentcard cells are rewritten: white-labeled card_enrollment, Face ID authorization, Agentcard executing the handoff, and reuse for recurring and one-time purchases.

Provider choice links switch from relative paths to https://hypeship.dev URLs, with slightly tightened wording around single-use vs multi-purchase flows. A new note calls out that both integrations may offer rewards and chargeback protection, with a pointer to each provider’s docs.
