fix(scripts): put the shebang on line 1 of panll-launcher.sh (#115)

A stray blank line above the shebang means the kernel never sees one, so the
script runs under whatever shell invoked it rather than bash (shellcheck SC1128).

Codacy note this answers: it flagged these as GENERATED files and asked for the
fix to go in the generator, or it would be reverted on the next re-mint. That is
now done - launch-scaffolder#27 fixes the shebang position in
templates/launcher.sh.tera and merged as a93e59fa. Regeneration therefore
reproduces this change instead of reverting it.

Verified before merge: Codacy 0 issues, Sonar quality gate passed, and the
failing checks on this PR are pre-existing on main - they are K9/A2ML manifest
validators whose annotations reference only .k9.ncl and .a2ml files, never a
shell script, and they fail identically on main.
