UX-08 phase 2a: short, plain notifications, and a ratchet for the rest

Every HA notification the add-on raises now has a title of at most 5
everyday words and a one-sentence body; a red alarm may use three so no
action is lost. The texts live in app/messages.py, the rule in STYLE.md,
and the detail that moved out in DOCS.md "Notifications", which each body
links to. No notification_id, trigger or cadence changed.

test_messages.py enforces the rule on every notification, fails any
notification worded outside app/messages.py, and ratchets the kinds not yet
rewritten (rows, banners, refusals, logs, options) through a shrinking
allowlist of 200. Six tests re-pinned from prose to meaning.
