Outage-count computations returned the wrong response shape

Previously, computing an SLA definition that uses the "service outage count" plugin returned broken results via the REST API:

• The response had the wrong shape entirely - it looked like a "service state percentage" result instead of an outage-count result.
• The requirement's threshold_count and allowed_duration were missing from the response entirely.
• The requirement's observed_state showed up as a plain number (e.g. "2") instead of the expected state name (e.g. "crit").
• An irrelevant monitoring_levels block, which only applies to the "service state percentage" plugin, was included in outage-count results too.

This has been fixed. Outage-count computations now return their own correct response shape, with observed_state, threshold_count, and allowed_duration all present and correctly typed.

CRIT results showed up as "writ" in state-percentage computations

Independently of the above, computing an SLA definition that uses the "service state percentage" plugin returned "writ" instead of "crit" for observed_state whenever the underlying rule was based on the CRIT state. This has been fixed as well.
