fix: added default protocol in the endpoint input field

[AbhishekPAnil]

This pull request improves how reconciliation service endpoints are handled by automatically adding the https:// protocol if a user omits it, making the system more user-friendly and robust. It also updates the user interface to clarify this behavior and adds a test to ensure the new logic works as expected.

Endpoint normalization improvements:

• Added a static normalizeEndpoint method to ReconciliationService that automatically prepends https:// to endpoints missing a protocol. The constructor now uses this method to standardize endpoints. [1] [2]

User interface updates:

• Updated the endpoint input field's placeholder in ReconciliationServiceInput.jsx to inform users that https:// is assumed if omitted.

Testing enhancements:

• Added a test to ReconciliationServiceInput.test.jsx to verify that endpoints without a protocol default to https://.
