Patch (v1.2.3): Controller Tooltips, Small Fixes

Hey everyone!

Quick small update. Was going to wait to release this with the achievements, but there really isn't a reason to delay it. Especially as it'll immensely improve the experience on Steam Deck.

Changelog

• QoL: Controllers can now use the left stick to navigate the unit info and promotion UIs, allowing them to hover icons to read tooltips, and toggle stats/growths.
• Fix: Cleaned up some more unused assets.
• Fix: Show correct dialogue portraits for "Kicking the Habit" support conversation.

Achievements are going well so far! I have them all in the Steam backend, for 30 total. Now just need to integrate with the Steam APIs and trigger them from code.

Best,
Eldin T.
