Description

Fixes a ValueError startup crash and subscription drop when registering multiple wildcard paths on the same pub/sub component with disable_topic_validation=True.

Previously, enabling this flag collapsed internal tracking keys down to the pub/sub identifier alone, causing map collisions and rendering the sidecar blind to subsequent subscriptions. This change standardizes discrete internal dictionary keys across all registration paths. It introduces a regex-based pattern matching fallback evaluation inside OnTopicEvent and _handle_bulk_topic_event to route events when direct string lookups fail.

Closes #436
