The tactical HUD has a bar top-right that provides icons for non-soldier-specific actions. Unfortunately, the current implementation relies heavily on hardcoded flash stuff but I think it can be overcome.

The API would be an event with an array of actions, each of which would contain:

• Icon
• Text
• Callback on usage
• Maybe more things, depends

For controller, if

• 1 action - show as "evac" text is shown in vanilla
• 2 or more - show "commander actions" and on RS press, bring up a pause-like menu, but filled with the options (including the default evac option)

For kb+m, the icons would be positioned starting after the "end turn" one and before the chosen icon. Note that this will require some manual positioning recalculations but I think that it's quite possible to do with a few unsolicited flash calls. For buttons themsleves, we can take inspiration from unused UITacticalHUD_CommanderHUD

Using this, we could also fix the lack of ability to open sitrep and chosen information mid-battle with controllers

This would require non-trvial changes in UITacticalHUD, UITacticalHUD_MouseControls and UITacticalHUD_AbilityContainer
