Pull request overview

This PR completes the refactoring work started in WPB-21964 by moving the TeamFeatureStore Cassandra interpreter from the Galley service to the wire-subsystems library. This promotes better code organization and reusability by placing the interpreter alongside the effect definition.

Changes:

• Moved Galley.Cassandra.TeamFeatures module to Wire.TeamFeatureStore.Cassandra in wire-subsystems
• Introduced TeamFeatureStoreError type to replace direct use of InternalError in the interpreter
• Removed TinyLog dependency from the interpreter (logging handled at higher application level)
