build: bump version to 4.4.7-ba7opf.15.7 (504)

resolvePerName crashed with NoSuchElementException (all.first()) when an
AMSAT live-page name had no matching local entry (TEVEL2-1..9, RS95S, any
brand-new sat not yet in the local TLE). The exception was swallowed by
updateAmSatLiveLists' runCatching, so the FM/Linear lists were NEVER
rewritten — they stayed at the stale pre-whitelist snapshot containing
all five ISS modules, which is why ISS kept showing as DESTINY despite the
15.4/15.5/15.6 disambiguation fixes.

Fix: return an empty set for names with no local match (correct skip
semantics) so the rest of the page still resolves and the ISS module
collapse runs. Regression test covers the real AMSAT page mix (ISS +
unknown names).
