A4A: Display ineligibility reasons in WooPayments commission status popover

[tiagonoronha]

Related to https://linear.app/a8c/issue/A4A-1609/woopayments-commission-eligibility-label-is-not-matching-site

Proposed Changes

• Update status popover to show specific ineligibility reason when available
• Allow customization of the link and link text per ineligible reason
• Maps error codes to user-friendly messages

Why are these changes being made?

• Agencies often struggle to understand why a site isn’t eligible. These changes will help add clear ineligibility reasons to the Agencies dashboard.
