Add a settlement and reconciliation status report

[StuartFerguson]

Summary

Add a report that helps merchants understand settlement and reconciliation status so they can quickly confirm whether their business is balanced.

User Value

Merchants need visibility into whether the host and local records are aligned, and whether any transactions are still pending or out of balance.

Scope

Create a report screen showing:

• Last reconciliation time
• Reconciliation result
• Settled transactions
• Pending transactions
• Failed transactions
• Variance amount if available
• Outstanding items needing attention

Mobile UX Requirements

• Show the current reconciliation status first.
• Present variance and exception items prominently.
• Use short labels and clear color/state indicators.
• Keep detailed breakdowns behind a drill-down action.

Acceptance Criteria

• Merchant can view the latest reconciliation status.
• Merchant can see whether the account is balanced or not.
• Any variance or outstanding issue is clearly shown.
• The report is readable and functional on a small screen.
• Host failures and missing data are handled gracefully.

Notes

This should align with existing balance analysis functionality where possible.
