What

Fill the empty YM-K1501 / V-SK152 test stubs and add a YM-K1501EU case, giving the three registered Smart Kettle product IDs real discovery coverage.

Why

These stubs have been vacuous passes since the 2022 import — they pass without asserting anything, so they hide regressions (e.g. an accidental removal of the kettle registrations in devices.py would go unnoticed). The Mi smart kettles broadcast no measurement objects over MiBeacon, so the parser can only identify them; there was no test proving even that worked.

How

A shared _assert_kettle_discovery helper synthesizes an unencrypted MiBeacon V4 discovery beacon (frctrl 0x4010, object_include=0) for each product ID (0x0083/0x0113/0x045C) and asserts the device is supported() and identified as a "Smart Kettle". Same discovery-only pattern as test_Xiaomi_ESM787_discovery. No parser changes — pure test coverage.

Testing

poetry run pytest tests/test_parser.py → 133 passed. black/isort/flake8 clean.

no measurement objects over MiBeacon, so a shared helper synthesizes an
unencrypted V4 discovery beacon (object_include=0) and asserts each
registered product_id (0x0083/0x0113/0x045C) is identified as a Smart
Kettle. Guards the device registrations against accidental removal.
