fix(reports): health report review fixes F2-F11

- FlowLoadResult ok/unavailable/failed + isRolloutError classification
- availability 'unknown' + flow_unmeasured reason instead of false greens
- telemetry none/fresh/lagging/stale; trustworthy requires a positive signal
- env-wide queue totals denominator; bucketCoverage with anomaly windows
- finishedPerMin drain math; canonical ReportViewModel/ReportPeriod schemas in core
- registry tables auth metadata; MCP prompt enum validation + escaping
- period grammar without seconds, 90d cap; new presenter/route/prompt tests

+Reports can now be fetched as structured data, not just text: ask for the `json` format and you get the numbers and what they mean, typed. Report periods are also stricter — the shortest window is one minute (`30m`, `1h`, `7d`), because reports summarise data by the minute and anything shorter can't be answered honestly.
