Migrate the AI Agent creation form to LS

[dan-niles]

Purpose

Resolves wso2/product-ballerina-integrator#1130

This PR introduces an update to the AGENT_CALL template, allowing it to include fields from the AGENT node template. This allows us to render the agent form in the frontend with agent fields like Role, Instructions, Max Iterations etc as well as agent call related fields like Query, Session ID etc. This updated node template can be used to generate source code for the default model provider + agent definition + agent call.

It also includes support for editing the agent definition in both local and module level scopes in the low code UI.
