feat(amsat): show consecutive same-status report count in status cells

Day-cell numbers now count the most recent consecutive reports sharing the
newest status (counting back from the newest report, stopping at the first
different status), instead of the total report count of the day. Empty gaps
do not break the streak; statuses compare by exact report text; counting
does not cross day boundaries.

- SatDay gains streakCount (computed in AmSatRepository.buildStatuses)
- DayCell renders day.streakCount instead of slot count sum
- Add real org.json to core:data unit tests (android.jar stub cannot parse)
- Add 2 streak tests: mixed-status slot breaks, all-same-status counts all
