fix(frontend): prefer top-level await over async IIFE in graphql-codegen config

[SuyashJain17]

Proposed change

Resolves #3087

This PR refactors frontend/graphql-codegen.ts to address SonarCloud rule
typescript:S7785 by replacing the async IIFE pattern with top-level await.

The change improves readability and aligns the configuration with modern ES
module standards, while avoiding unnecessary async wrapper functions.

This is a refactor-only change; no functional or behavioral changes are intended.

Walkthrough

Replaces an async IIFE default export in frontend/graphql-codegen.ts with a named async function getCodegenConfig exported as default; CSRF fetch failures now throw Errors (including status/statusText) instead of returning early; removed immediate invocation and adjusted error propagation.

Changes

Cohort / File(s)	Summary
GraphQL codegen entry frontend/graphql-codegen.ts	Replaced exported async IIFE with a named async function getCodegenConfig exported as default; added explicit error throwing on CSRF fetch failure and non-OK responses; removed immediate invocation so function is no longer invoked at module load.

In `@frontend/graphql-codegen.ts`:
- Around line 71-74: The catch block that logs "Failed to fetch CSRF token..."
leaves the exported config undefined; modify the catch inside the async
initialization so it re-throws the caught error (or throw a new Error that wraps
the original) instead of only console.logging, ensuring the failure surfaces
rather than exporting undefined from the module (look for the catch near the
CSRF fetch and the exported config variable).
- Around line 5-8: Top-level await in the current module (the use of await when
fetching CSRF and the top-level variable config) breaks graphql-codegen 6.1.1;
refactor by replacing the module-level await and variable with an exported async
function (export default async function()) that performs the fetch to
`${PUBLIC_API_URL}/csrf/`, builds and returns the CodegenConfig object (do not
return undefined on fetch failure—either throw or return a sane default config),
and move all logic currently in the top-level try/catch into that function so
graphql-codegen's jiti loader can evaluate it correctly.
