improvement(billing): duplicate checks for bypasses, logger billing actor consistency, run from block

[icecrasher321]

Summary

• Run from block should call preprocess executions for billing checks

Greptile Overview

Greptile Summary

This PR strengthens billing integrity by adding duplicate subscription checks, ensuring billing actor consistency, and extending billing enforcement to run-from-block executions.

Key Changes

• Run-from-block billing enforcement: execute-from-block route now calls preprocessExecution to enforce billing checks, usage limits, and rate limits before execution
• Duplicate subscription prevention: Added hasActiveSubscription checks across checkout, subscription transfer, and organization creation flows to prevent multiple active subscriptions on the same referenceId
• Logger billing consistency: ExecutionLogger now uses workspace billed account resolution (via getWorkspaceBilledAccountUserId) matching the preprocessing logic
• Consolidated blocking helpers: Created blockOrgMembers and unblockOrgMembers functions to centralize organization member blocking/unblocking logic
• Enhanced dispute handling: Dispute webhook now blocks all org members (not just owner) and handles warning_closed status for unblocking
• Organization deletion safety: Subscription deletion now checks for other active subscriptions before deleting organizations

Architecture Impact

The changes consolidate billing logic into reusable helpers and ensure consistent billing actor resolution across execution paths. The duplicate subscription checks create multiple defense layers at authorization, checkout, transfer, and organization creation points.

Confidence Score: 5/5

• Safe to merge - improves billing integrity with defensive checks
• All changes are defensive improvements to billing logic. The duplicate subscription checks prevent edge cases, billing actor consistency ensures correct cost attribution, and the run-from-block enforcement closes a bypass. Code is well-structured with proper error handling.
• No files require special attention
