fix: add 8s timeout to NeoInstituteContext school node fetch

Browse Source 
Races the SchoolNeoDBService.getSchoolNode() call against an 8-second
timeout. If Neo4j is slow or unavailable the workspace now loads within
seconds rather than waiting for the full axios 120s timeout. The context
degrades gracefully — workspace opens without institute data, error is
logged as a warning not an exception.
