Subject: [PATCH 1/4] fix(rewards): surface fetchAll errors via error state

fetchAll swallowed balance/history fetch failures with console.error,
leaving the UI stuck on empty data with no error indication. Set the
existing error state in the catch block and clear it on success.

Subject: [PATCH 2/4] fix(auth): return null from executeRefresh on refresh
 failure

When token refresh failed and isTokenExpired returned false (e.g. JWT
with no readable expiry), executeRefresh returned the stale token.
Callers then retried with a dead token, creating a silent 401 loop.
Return null so callers can disconnect instead.

Subject: [PATCH 3/4] fix(courses): guard getCourseModules against missing
 modules array

course.modules.sort() threw when the API omitted the modules field,
crashing the module list page. Default to an empty array so missing
modules return [] instead of throwing.

fetchEnrollments swallowed failures with console.error, so users never
