Add tests for all() orderBy/pagination; update Fjell dependencies

This release adds unit tests to verify orderBy serialization and pagination behavior in the all() operation, and updates Fjell package dependencies.

Testing Improvements

• Add tests/ops/all.test.ts to verify all() orderBy handling and pagination (commit e29fc7f)
  • Verify orderBy serialization in request params for single field, multiple fields, and empty array
  • Assert coexistence with limit/offset via allOptions and with compoundCondition; validate params via queryToParams
  • Check response metadata passthrough and backward compatibility when orderBy is omitted, with an empty query, and with only limit
  • Include mocked HttpApi, ClientApiOptions, Utilities, and a minimal logger mock
