Creates the full audit lifecycle component bundle used by product entrypoints.

resources is product-defined. It commonly contains a database connection and runtime config snapshot. record_server_start and record_server_shutdown record the product’s own lifecycle audit entries. flush_audit_manager drains the product’s buffered audit writer. With the mail-outbox-dependency feature enabled, the shutdown audit phase automatically runs after the mail outbox drain component.
