fix: resolve each team independently to prevent squadron_long order inversion

When one team has a dash-tag (e.g. -DSPLA-) and the opponent has a normal
tag (e.g. ALUN2), batching both into resolve_clans caused the short-name
pass to place the normal team first in results and the tag pass to append
the dash-tagged team second — inverting the mapping vs. the teams array.
Each team's players were then looked up against the wrong squadron's API,
yielding curr=0 for everyone and diffs=0 on the scoreboard.

Fix: resolve each team concurrently and independently so results are always
index-aligned with the teams list regardless of which resolution path fires.
Also propagates squadron_short to the scoreboard renderer so display names
are clean (DSPLA not -DSPLA-).
