docs: record the Blue Archive source assessment

bluearchive.fandom.com/wiki/Event/Event_List fetches and parses cleanly,
so the reason to decline it is not obvious from trying it: every one of its
88 rows is JP-server history, the newest ending 2026-02-18, so it yields
zero live or upcoming events. That reads as an empty lane plus a
permanently rejected snapshot, since the runner rejects a body parsing to
nothing — a failure mode worth naming in the assessment table, because
"clean table, no error" invites writing the adapter first.

bluearchive.wiki is the live alternative and stays unbuilt for now: it is
Miraheze, its robots closes the API route we used for Fandom, and it lists
JP and Global in separate tables — the akwiki hazard, which wants settling
before a line is written rather than after.

Its `Event/Event_List` is a JP-server archive whose newest entry ended 2026-02-18, so all 88 rows are history and it yields **zero** live or upcoming events. An adapter would put an empty lane on the calendar and, because the runner rejects a body that parses to nothing, report a broken source forever.
