[Transaction Stream Service] Focus contract address confusingly ignores wrapped calls

Description

The focus contract address alpha feature is presumably intended to simplify client filtering behavior: only events corresponding to a particular Move package are allowed through the top-level worker process

However, the underlying implementation appears to filter based on the public entry function rather than by the event address. E.g. if a project composes on top of another and invokes the underlying package via a wrapped function call, then the wrapping package's events (which are also the wrapped package's events) get removed

Instead, it is suggested that filtration rely on the address of emitted event types, or alternatively, the focus_contract_addresses be renamed to something like entry_function_address with an additional event_type_address
