Change cron schedule from 4x daily (0,6,12,18 UTC) to 8x daily
(every 3 hours) to keep body battery and other Garmin data fresher.

- Add 15-minute notification granularity (*/15 cron) so users get emails
at their configured time instead of rounding to the nearest hour
- Add DailyLog fallback to most recent when today's log doesn't exist,
preventing 100/100/Unknown default values before morning sync
- Show "Last synced" indicator when displaying stale data
- Change Garmin sync to 6-hour intervals (0,6,12,18 UTC) to ensure
data is available before European morning notifications

Sync at 08:00, 14:00, and 22:00 UTC instead of every hour.
Garmin data updates once daily so hourly was excessive.
