feat(measurements): add a COMPUTED source and first-class score types

Add a server-owned COMPUTED measurement source for rows a server engine
derives rather than a device or a person reports, plus three first-class
0-100 score types — RECOVERY_SCORE, STRESS_SCORE, STRAIN_SCORE (unit
"score", plausibility range 0..100).

COMPUTED is read-only from a client's perspective: it joins the read /
decode enum so the native client can decode the rows it queries and
charts, but every client-facing write surface rejects it exactly like
WITHINGS and IMPORT — the batch ingest allowlist stays {APPLE_HEALTH,
MANUAL} and the single-entry POST 422s a COMPUTED source.

All three score types thread through every type-exhaustiveness site: the
unit + plausibility-range maps, the PR-direction resolver (scores carry
no record direction, like the device events), the category overlay (a
new "scores" cluster), the list-view label / icon / colour maps with
locale strings across all six bundles, and the insight chart-token
allowlist + orphan-enum stripper. They are not clinical vitals, so they
stay out of the doctor-report PDF.

Only the recovery score is computed today; the stress and strain types
are defined now so the engines that compute them later need no schema
change. Migration 0106 is purely additive (ADD VALUE IF NOT EXISTS).
