Snapchat assigns sequential IDs that happen to overlap real epoch
values, so the 10-16 digit timestamp regex matched and produced
2002-era dates for files actually saved in 2016/2021. The digits
themselves are indistinguishable from a unix timestamp, so we
dispatch on the source-app prefix instead. Case-insensitive,
extensible for future apps that exhibit the same pattern.

Reported cases:
Snapchat-1021849065.mp4 → 2002-05-19 (actual 2021)
Snapchat-1751031586660373917.jpg → 2002-09-09 (actual 2016)
