feat(button): add "Refresh status" button for mowers

Adds a Refresh status button (button.<mower>_refresh_status) for
Luba/Yuka mowers, mirroring the existing spino_refresh_status button
the Spino pool cleaner already exposes.

Pressing it calls coordinator.async_ensure_fresh_state(), which fires a
one-shot report snapshot only when the cached device state is older than
2 minutes (a no-op while a BLE report stream is already feeding fresh
data).

Rationale: the integration is local_push, so a docked/idle mower stops
emitting report_data.dev/.work frames and lawn_mower/activity_mode/
charging/progress freeze at the last snapshot while the connect/RSSI
heartbeat keeps updating. There is currently no user-facing way to pull
a fresh status on demand: homeassistant.update_entity only reads cached
push data, and the map/schedule/RTK sync buttons refresh different data.
The only existing way to force a dev refresh is to send a motion command
(start/dock/pause). This exposes the gentle refresh primitive on its own
so users and automations can bring status current without commanding the
mower, bringing mowers to parity with the Spino.
