Return the formation command list.
When formation ~= 'NoFormation', FormationCommands.UnitsFormationOrder returns a command table, but Platoon:IssueAggressiveMoveAlongRoute discards it and returns nil. This violates the SimCommand[] contract and prevents the result from being passed to CheckCommandsCompleted, which iterates the command table. Return the helper result.

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.

- Created a new file with helper functions for formation commands that orient the formations correctly by angle on each node. - Refactored platoon and ScenarioFramework to use the new formation commads. - Attack platoons in campaign now orient formations correctly, so units move through path nodes faster.

Description of the proposed changes
Additional context
Platoons already had helper functions to Issue various formation commands with proper formation orientation, this PR extracts that code into it's own module, so its easy to use from elsewhere. It also removes the code repetition that was present in the existing functions
