The live tennis-draw sync now fans eliminations out to mirror windows, but the
admin bracket UI is a second live scoring path: when an admin enters match
results for a shared qualifying major, mirror windows already receive
"Qualifying Points Update" posts via the fan-out, yet the "Knocked Out" section
was still dropped there.
Thread the newly-decided losers (losers of matches reaching completion for the
first time this action) through the admin route's fanOutMajorIfPrimary calls in
the set-winner and set-round-winners intents, reusing the same per-window
elimination translation. Re-scores, complete-round, reprocess, and finalize
decide no new losers, so they pass nothing and never re-announce an exit —
mirroring populateBracketFromDraw's first-completion rule.
Extract the first-completion decision into a pure newlyDecidedLosers() helper
shared by both intents and unit-tested directly.

Mirror tournament windows (leagues drafting the same real-world major)
announced Qualifying Points awards but silently omitted the "Knocked Out"
section. Knockouts are derived only on the primary window's bracket
(playoff_matches → newlyDecidedLoserIds); mirrors receive placement/rawScore
only, so a player eliminated in a non-scoring round (0 QP) becomes a
null-placement filler indistinguishable from "not yet played" — the mirror
has no local signal to detect the knockout, and its notification was also
gated on QP having changed.
Thread the primary's newly-eliminated participants down the fan-out
(syncTennisDraw → fanOutMajorIfPrimary → syncMajorFromPrimaryEvent →
syncTournamentResults → processQualifyingEvent), translating identity across
window boundaries (primary season_participant → canonical participant → each
mirror's season_participant), and relax the mirror notification guard to fire
on eliminations even when no QP changed — matching the primary path.
Reuses the same notifyQualifyingPointsUpdate the primary already calls, so
mirrors now produce the same combined "Points Awarded" + "Knocked Out" embed.
