fix(partnerConfig): fix fetchPartnerData query to prevent undefined URL Error

[aeddaqqa]

This PR addresses an issue where the fetchPartnerData query was sometimes resulting in a "Cannot read properties of undefined (reading 'url')" error. The main changes include:

• Enhanced error handling in the query function to ensure it always returns a valid URL or throws a meaningful error.
• Added checks to verify the availability of required data (like selectedNetwork) before use.
• Wrapped the transformResponse function in a try-catch block to handle potential errors during data transformation.
• Improved error reporting in components using this query.
