v1.2.10 - set_bedtime edits the weekly schedule (#129) + TrackerEntity deprecation fix (#130)

Fixed

• set_bedtime now updates the recurring weekly schedule (#129). It previously posted only a per-day "tonight only" override, so it reported success but the weekly schedule in Family Link never changed. set_bedtime now defaults to editing the recurring weekly schedule for the target day. New scope option: weekly (default) edits the weekly schedule; today posts a one-off override for that day only (old behavior).
• Removed deprecated TrackerEntity import (#130) - was scheduled for removal in HA Core 2027.6; now imported from the supported location.
