andreas de778f680f fix: reduce default hysteresis 10%→2%; show recovery threshold in alerts UI
The 10% default hysteresis created an unreasonably wide recovery band:
a 95% threshold would only clear once the value dropped below 85.5%,
causing alerts to linger long after the metric was well below the
trigger level.

Change default hysteresis to 2% across all threshold parsers (plugin
metrics, partitions, RTT). For a 95% threshold, recovery is now at
93.1% instead of 85.5%.

Add AlertState.hysteresis field (set on every check, cleared on OK) and
expose recovery_threshold in to_dict() so the Alerts dashboard can
display "recovers < 93.1" alongside the trigger threshold, making the
hysteresis band visible to the user. Pickle backward-compatible via
__setstate__.
