Subject: [PATCH] fix(lightning overlay): correct timestamp scaling and more

- converts incoming timestamp from nanoseconds to milliseconds
- adjusts displays to use timestamp instead of age
- removes the now unused age from strike objects
- adjust time limit to a constant 30 minutes to match panel text

The memory imposed limit should be on the size of the array, not the age.
