revert(insights): drop hydration logging

Remove the in-app water-intake logging feature: the WATER_INTAKE
measurement type, the per-user daily-goal field, the goal-ring card and
its endpoint, and the related query keys, OpenAPI route, and locale
strings. The feature is dropped from this release; the baseline-drift,
breathing-screening, and labs-changes insight cards are unaffected, and
the pre-existing TOTAL_BODY_WATER body-composition type stays intact.

-/**
- * v1.25 — hydration daily-goal surface.
- *
- *   GET  /api/hydration  → today's summed water intake vs the user's goal.
- *   PATCH /api/hydration  → set the per-user daily goal (ml).
- *
- * Logging itself rides the existing measurements create path (POST
- * /api/measurements with `type: "WATER_INTAKE"`, unit "ml") — this route only
- * reads the day's total and owns the goal. `userId` is always narrowed from
- * `requireAuth()`; the goal is built field-by-field, never mass-assigned.
