This assertion is unnecessary since it does not change the type of the expression

The bug :-
The `useDjangoSession` hook contains redundant type assertions (as `ExtendedSession`) that do not change the inferred type of the expressions. Sonar flags this under rule `typescript:S4325` as a minor code smell, since TypeScript already understands the types in this context.
This results in unnecessary code noise and reduced maintainability.

This can lead to:
• Reduced readability
• Harder debugging
• Unnecessary type assertions
• Sonar rule violation: typescript:S4325 (minor code smell)

Location :-
• File: `frontend/src/hooks/useDjangoSession.ts`
• Line: 27,87,80

To Reproduce :-
• Run SonarQube / SonarCloud scan

Check violations for `typescript:S4325`
Observe redundant type assertion at line 80

Expected behavior :-
Redundant casts and non-null assertions should be removed when they do not affect type inference. TypeScript’s contextual typing should be relied upon instead.

Proposed Solution :-
Remove unnecessary as `ExtendedSession` assertions and rely on TypeScript’s inferred types, or assign the session to a properly typed variable once and reuse it to avoid repeated redundant casts.

Hi @arkid15r
Shall I work on this?

Start with frontend/src/hooks/useDjangoSession.ts at the reported lines 27, 80, and 87, and inspect how the session value is typed. Run a SonarQube or SonarCloud scan and check rule typescript:S4325. Done means the redundant ExtendedSession assertions and non-null assertions no longer produce violations without changing behavior.
