Marc-André Bombeck c254135406 feat(environment): resolve past days conservatively, never guessing from home ...

Rework the per-day location resolution so it can no longer fabricate weather for
days before the home was set. Precedence, first hit wins:

  1. an explicit dated location period (a trip, or a corrected stretch of
     history) covering the day;
  2. DEVICE — a reserved slot for a future client-supplied coarse per-day
     location (ranks between the period and home; not produced server-side yet);
  3. the home location, but only for days on/after its effective-from date;
  4. otherwise the day is skipped.

The home route stamps `homeSince` whenever the home is set/updated and returns
it. The overview exposes it. Backfill bounds are now optional and default to the
conservative `[homeSince .. today]` span instead of a fixed reach onto the
current home; days before `homeSince` still resolve to a skip in the worker, so
even a wider explicit start cannot back-fill weather for the pre-home past. To
reach further back a user adds an explicit location period for that range.

Add unit coverage for the precedence (including the effective-from boundary and
the skip-not-guess rule) and the default backfill range.
