Account Password Update Functionality

Add the ability to update prop firm account passwords within PF1 after accounts have been initially connected and configured. Currently, there appears to be no option to modify account credentials once a prop firm evaluation account has been set up in the platform, which creates issues when users need to change their passwords for security reasons or when prop firms require password updates. This feature should include an "Edit Account" or "Update Credentials" option in the account settings that allows users to securely modify their login information without having to remove and re-add the entire account connection, maintaining account history and configurations while ensuring continued platform access.
