[logical] Introducing physical optimizer support for logical tables

[shauryachats]

Summary

This PR enables the physical optimizer to work correctly with logical tables by making the physical planning and worker assignment logic aware of logical to physical table mappings.
The leaf-stage worker assignment is updated to resolve logical tables, compute routing across all underlying physical tables, and produce deterministic worker to segment assignments, while fragment metadata is extended to carry logical-table specific segment mappings.

Figuring out a way to assign distribution for a logical table still needs some investigation - hence will be picked up in a follow-up PR.

Testing

Adds integration coverage to validate that common query patterns work with logical tables under the physical optimizer. Also added unit tests.
