Do not exit after the first selected squad.

When squad is omitted, GetSquadsForFormationOrder selects all platoon squads. Each NoFormation branch returns after the first non-empty squad, so all remaining squads receive no route commands.

  • lua/ScenarioFramework.lua#L525-L527: use an else branch and continue the squad loop after GroupMoveRoute.
  • lua/ScenarioFramework.lua#L553-L555: use an else branch and continue the squad loop after GroupPatrolRoute.
  • lua/ScenarioFramework.lua#L577-L579: continue the squad loop after GroupAttackRoute, and preserve the documented last-command return value instead of returning {}.

In `@lua/ScenarioFramework.lua` around lines 525 - 527, Update the squad loop in
lua/ScenarioFramework.lua at lines 525-527, 553-555, and 577-579: replace the
early returns in the NoFormation, patrol, and attack branches with else-based
continuation so every selected squad receives its route command. In the attack
branch, continue processing all squads while preserving and returning the
documented last-command result instead of returning an empty table.
