After the ingester._sleep alias fix, three tests in test_service_isolation.py
still patched `decnet.web.ingester.asyncio.sleep` (the old global-singleton
path). The ingester now calls `_sleep` directly, so those patches no longer
controlled the ingester's sleep — the worker looped with real asyncio.sleep
and the tests hung indefinitely.
Also: four API lifespan tests had no tarpit_watcher_worker patch, letting the
real tarpit task start. And test_api_survives_db_init_failure patched
`decnet.web.api.asyncio.sleep` (the singleton) instead of the existing
`_retry_sleep` alias.
Fixes:
- patch("decnet.web.ingester._sleep", ...) in the three ingester tests
- add tarpit_watcher_worker patch to all four api lifespan tests
- patch("decnet.web.api._retry_sleep", ...) in db_init_failure test
