chore: improve validateCyclic & fix on query parser & upstream resolver

[ahmadnaufal]

Summary

This PR's main change is to make the job cyclic dependency check work on a global optimus instance scale, not on tenant level only. With this change, there are also stability fixes on the optimus job validate

Fix cyclic dependency validation to be global-scoped

• Cyclic dependency previously works only on tenant-level due to GetAllByTenant jobs
• Instead of tenant only, now the cyclic checks are based on global cross-project jobs by using a new function JobRepository.GetAllResolvedUpstreamEdges. New detected dependencies are built using JobService.BuildGlobalUpstreamGraph so that cyclic dependency check will also work with newly added upstreams

Query parser: exclude UDFs / nested struct columns to be parsed as upstreams

• Current query parser keyword-less case (needed to support comma-joined FROM a, b, c lists) had no way to tell a genuine table reference apart from any other three-dotted expression elsewhere in the query — so SELECT a.b.c, a.d.e FROM ... picked up a.b.c and a.d.e as invalid upstream tables.
