Issue:
Bug: [CYPRESS]: Verify Search in "Payment operations" page.



---

### **Title**: Verify Search in "Payment operations" page.

---

### **Description**:

This task is to write and execute automated test cases for various UI elements and functionalities on the "Payment Operations" page. The tests should validate that key UI elements are present and that core functionalities operate as expected.

### **Objective**:

Ensure that the "Payment Operations" page displays all key elements and that interactions like searching, filtering, and report generation work as intended. The task will include multiple test cases covering these areas.

### **Pre-requisites:**

[Create a dummy connector](https://github.com/juspay/hyperswitch/issues/6125)
[Use the SDK to process a payment](https://github.com/juspay/hyperswitch/issues/6124)

---

### **Test Cases**:


#### **Test Case 1: Search for Payment Using Existing Payment ID**

- **Pre-requisites**: Make a payment.
- **Steps**:
  1. Login to the application.
  2. Navigate to the "Payment Operations" page.
  3. Enter an existing payment ID into the search bar.
- **Test Data**: {{payment_id}}
- **Expected Results**:
  - Payments table should contain one row with valid payment details.

#### **Test Case 2: Search for Payment Using Invalid Payment ID**

- **Pre-requisites**: User is logged in.
- **Steps**:
  1. Navigate to the "Payment Operations" page.
  2. Enter an invalid payment ID or string into the search bar.
- **Test Data**: "abacd," "something," "createdAt"
- **Expected Results**:
  - "There are no payments as of now" text should be displayed.
  - "Customize columns" button should not be present.

---

### **Acceptance Criteria**:

1. All test cases should pass with the expected results.
2. Each test case must verify the required functionality or UI element.
3. The tests should be included in the regression suite and executed in the CI/CD pipeline.

Pull request description:
## Type of Change
<!-- Put an `x` in the boxes that apply -->

- [x] Refactoring

## Description
<!-- Describe your changes in detail -->
This PR will remove the multiple mca feature. No fields will have default values in primary business details.
- When creating merchant connector account, `business_label` and `business_country` are mandatory. A validation is added to ensure that the business details passed when creating connector account, are configured in the merchant account.
- When creating the payment, if no business details (`business_country` and `business_label`) are passed then take it from the merchant account. If more than one business details are configured in the merchant account, then raise an error mentioning that business details are mandatory. 


## Motivation and Context
<!--
Why is this change required? What problem does it solve?
If it fixes an open issue, please link to the issue here.

If you don't have an issue, we'd recommend starting with one first so the PR
can focus on the implementation (unless its an obvious bug or documentation fix
that will have little conversation).
-->


## How did you test it?
<!--
Did you write an integration/unit/API test to verify the code changes?
Or did you test this change manually (provide relevant screenshots)?
-->
