[TOOL-3689] Dashboard: Keep switch in disabled state if field value is empty in Sponsorship rules form (#6535)

<!-- start pr-codex -->

## PR-Codex overview
This PR focuses on improving the `transformedQueryData` computation by filtering out empty values from the `policy` properties. It enhances data handling for `allowedContractAddresses`, `allowedWallets`, `blockedWallets`, and `allowedChainIds`, ensuring cleaner and more accurate data is returned.

### Detailed summary
- Refactored `transformedQueryData` to filter out empty values from `allowedContractAddresses`, `allowedWallets`, `blockedWallets`, and `allowedChainIds`.
- Simplified return conditions for these properties.
- Changed handling of `allowedChainIds` to return an empty array instead of null to prevent API issues.
