chore: refresh the five sources that were due

Eleven sources were inside the 6h floor and were left alone. Of the eight the
runner planned, five answered: Reverse: 1999, GFL2, Stella Sora, Chaos Zero
Nightmare and Umamusume — the last four getting their first snapshot, so those
games stop being built from checked-in fixtures.

Fate/Grand Order, Infinity Nikki and Nikke were skipped on a 403 from
robots.txt, which is the documented Fandom posture and fails closed as intended.
Reverse: 1999 is the one Fandom wiki that answered this time; its page bytes
moved but it parses to the same six events, so nothing on the calendar changed
for it.
