Bugfix: SQL not rendered in Rendered Templates view

[sarth-akvaish]

This PR resolves the issue of not rendering SQL (other also like bash command) in the Rendered Templates tab in the specific Task.

Fixes : #60589

What is happening currently ?

Rendered Template fields are generated inside the task runner after jinja rendering and then sent to the API server to be stored in the RTIF table.

The task runner only serialized the top-level template fields defined on the operator(for ex - configuration)
Nested renderer paths (such as configuration.query.query) were not extracted or sent.

As a result The RTIF model and UI were functioning correctly, but the required data never reached them.

What changed made

The task runner logic si updated to corrrectly capture rendered template values after rendering and senfd them to the API server.
Becuase the UI is data driven, it immediately began displaying the correct rendered templates with proper title and syntax, without any changes in teh UI code.
