fix: bump athena-client utils dep to 1.96.3 (#1379)

## Summary

- Bumps `@adobe/spacecat-shared-utils` dependency in athena-client from
`1.82.1` to `1.96.3`
- v1.96.3 includes the temporal condition month/week wrap-around fix
(from #1376) with the aggregation granularity revert (from #1378)

## Context

Part of the PTR temporal series bugfix. The athena-client consumes
shared-utils via npm (not workspace link), so this explicit bump is
needed before downstream consumers (spacecat-api-service) can pick up
the fix.

## Test plan

- [x] All 180 athena-client tests pass with 100% coverage
- [x] No code changes — dependency version bump only
