Simplify customHeaders parameter type from Dictionary<String, List<String>> to Dictionary<string, string>

[Copilot]

The customHeaders parameter in API-related methods required Dictionary<String, List<String>>, forcing users to wrap single header values in lists unnecessarily.

Changes

• DataManagementTools.cs: Updated parameter type from Dictionary<String, List<String>> to Dictionary<string, string> in:

  • ExecuteWebApi
  • CreateRecord
  • UpdateRecord
  • UpsertRecord
  • DeleteRecord

• DataManagementHelper.cs: Added ConvertCustomHeaders to transform simplified headers to the format expected by ServiceClient.ExecuteWebRequestAsync

Usage

Before:

var headers = new Dictionary<string, List<string>> 
{
    { "Prefer", new List<string> { "return=representation" } }
};
await CreateRecord(client, "accounts", payload, headers);

After:

var headers = new Dictionary<string, string> 
{
    { "Prefer", "return=representation" }
};
await CreateRecord(client, "accounts", payload, headers);

This section details on the original issue you should resolve

<issue_title>Modify the customHeaders method argument in API related methods</issue_title>
<issue_description>- Change the argument data type for customHeaders method argument from Dictionary<String, List> to Dictionary<String, String>.

• The change should be done in the following methods:

1. ExecuteWebApi()
2. CreateRecord()
3. UpdateRecord()
4. UpsertRecord()
5. DeleteRecord()

• Additional custom headers can be sent using customHeaders argument as a Dictionary. Key is the header name. Value is the header value string. If a Header contains multiple values pass it as comma-separated string. For eg: Multiple Prefer headers can be specified using comma-separated values; for example: Key = Prefer , Value = respond-async,odata.include-annotations="*"
• Update the Description Attribute for the customHeaders argument such that the LLM agent should understand the syntax correctly and pass the values accordingly.
• update the method implementation to convert the Dictionary<String, String> to Dictionary<String, List> before passing it into ExecuteWebRequestAsync(). comma-separated string value should be converted to List.
• Also make any other appropriate changes to the logic if needed.
