fix(api): publish what the GET handlers send

A response parsed against its own registered schema disagreed in thirteen
operations. Where the handler was right, the schema now says so; where the
handler had drifted from its siblings, it follows them.

Schema:
- measurements list and detail declare aggregationProvenance
- series-batch and sleep night stages are partial records: only the
  requested types and the recorded stages are present
- medications declare deliveryForm, the injection-site fields, externalId,
  externalSource, the low-stock bookkeeping, schedules[].doseWindows and
  nextDueScheduleId on the list
- notification prefs declare coach.nudgeAiComposed and measurementReminder
- mood insights correlations declare suppressed
- record settings profile.unitPreference is nullable, as stored
- insights/comprehensive describes the computed overview it returns rather
  than the model digest fields it never sends

Handler:
- GET /api/mood-entries/{id} shares the list projection and now carries
  tagKeys and ratedFactors
- GET and PATCH /api/custom-metrics/{id} carry latest and entryCount
- /api/analytics no longer leaks anomalyCount through the per-night sleep
  summary and the glucose meal-context split
