rename feedback view to return success messages after running queries that do not return anything

[danvergara]

Add feedback page

Description

This PR introduces a new feedback view to provide users with more informative messages about the execution of their SQL queries. Previously, the UI only had an error page, which was displayed for both errors and successful queries that didn't return any rows. This could be confusing for users.

The new feedback view replaces the error page and provides the following features:

• Displays error messages in red when a query fails.
• Displays a success message in green when a query is executed successfully but doesn't return any rows.
• The content page is displayed as usual when the query returns results.

This change improves the user experience by providing clearer feedback on the query execution status.

How Has This Been Tested?

I have tested this feature by running the following queries:

• A query that returns results.
• A query that returns no results (e.g., SELECT * FROM users WHERE 1 = 0).
• A query that produces an error (e.g., SELECT * FROM non_existent_table).
