docs(TASK-047): mark Done in index; fix hooks table source file refs

Mark TASK-047 as Done in specs/tasks/_index.md (was stale "Not Started").
Update the §4.10 phase table in specs/architecture/04-components/hooks.md
to reference webserver_body_pipeline.cpp for request_received and
body_chunk — the correct location after the webserver.cpp refactor.
