Deferred: Breaking Changes

Carryovers from prior syncs plus one new this cycle (realtime-kit).

Resource	Change	Status
api-gateway	discovery.operations.edit() removed	carryover
cache	originCloudRegions.create -> update, bulkEdit -> bulkUpdate, edit removed	carryover
billing	usage.paygo endpoint URL changed (also adds non-breaking usage.get)	carryover
email-security	InvestigateListParams.action_log query param removed	carryover
realtime-kit	livestreams.getLivestreamAnalyticsComplete params end_time/start_time changed from string (ISO) to number (Unix timestamp)	new this cycle

Note on realtime-kit: it also adds a new non-breaking getLivestreamAnalyticsDaywise method. Held back because of top-level resource boundary.

Deferred: Codegen Regression

Resource	Root Cause	Status
addressing	RegionalHostnames and Regions classes still generated empty	carryover
