v0.1.1

Added

• Time format and temperature unit are now per-user preferences, joining
  the existing per-user language picker on /account → Formato de hora y
  temperatura. Each user can independently force 12H / 24H or Celsius /
  Fahrenheit regardless of the UI language. Defaults to Automático —
  which honours the active i18n bundle's native conventions (en-US → 12H +
  °F, es-ES → 24H + °C) — so existing users keep what they have without
  any action. Backed by two new endpoints (PUT /api/auth/me/time-format,
  PUT /api/auth/me/temperature-unit) and surfaced in /api/auth/me.
• Every hour-of-day display in the app now honours both the locale's hour
  cycle and the explicit override above: dashboard widgets, calendar
  events, tablet clock + events + tasks + recent messages, the wall
  (message and comment timestamps), tasks list, school timetables,
  member detail, member agenda, weather sunrise/sunset, account API-key
  "last used", calendar sync status. (#12)

Fixed

• All-day Google Calendar events no longer display one day early for families
  whose timezone is west of UTC (e.g. Christmas Day appearing on December 24
  in America/New_York). All-day dates are now interpreted in the family's
  timezone instead of falling back to UTC, and the API exposes a
  startDate / endDate (YYYY-MM-DD) pair the SPA renders verbatim — no
  more browser-side timezone shifting. Existing rows correct themselves on
  the next Google Calendar sync; no manual action required. (#13)
