[No QA] Docs updates for E/A#96901 clarify cross-border reimbursement payment message

[MelvinBot]

Explanation of Change

Documentation follow-up for #96901, which changes the auto-generated payment message on a cross-border reimbursement so it shows the exact amount credited to the employee (in their own deposit currency) plus the last four digits of both the company account it was paid from and the employee account it was deposited into — instead of the report total.

The Global Reimbursement - Setup and Verification article already has an FX-focused FAQ explaining why the reimbursed amount differs from the report total, but nothing explaining that the report's payment message itself now names that credited amount and both accounts. This PR adds one FAQ entry to close that gap, so a customer reconciling a cross-border payment understands why the message shows an amount that differs from the report total.

• Adds ## Why does the payment message on a cross-border report show a different amount than the report total? to docs/articles/new-expensify/wallet-and-payments/Enable-Global-Reimbursement.md, right after the existing "Why is the reimbursement amount different from the expense amount?" FAQ.

No other help-site changes are needed: this is a copy-only refinement of a system-generated report message for an already-documented behavior, with no new setting, workflow, or configuration.
