[chore] Add debug logs sandbox catalog updates

[matthewlouisbrockman]

Adds debug logging to the two ways we can update the sandbox catalog:

• the sandbox sync
• normal sandbox lifecycle routes

This helps us understand what causes 404s when it looks like the sandbox should be present in the catalog but isn't.

PR Summary

Low Risk
Low risk: adds debug-level logging around sandbox sync reconciliation and sandbox catalog store/delete operations, with no behavioral changes beyond extra log volume.

Overview
Adds targeted debug logging to help diagnose cases where sandboxes appear missing (404s) by emitting structured logs when sync expires or re-adds sandboxes and when the sandbox catalog is updated (store/delete) in both memory and Redis implementations, including sandbox.id, team.id, and node.id fields for correlation.
