jackett, bazarr, ombi: full nox modules (ADR 0044/0046)

Ported their real HTTP APIs (hal carried no client for these). jackett: an
indexer proxy — tools only (list indexers, search), no events, no broker
account, because it answers queries and has no timeline to observe. bazarr:
subtitle tools + emits module.bazarr.subtitle.downloaded (poll history, diff).
ombi: request tools + emits request.created/.approved. All pure emitters
(their decisions originate here). Typecheck; manifests parse.
