scenario editor: place units, rotate or garrison them

Description

The UI features a layout that prioritizes functionality for managing game elements, specifically a unit representation.

Player Information Section: At the top, it displays "Player 1" alongside a dropdown label indicating the civilization type ("Britons"). This provides contextual information for the user regarding which player's units are currently active.
Unit Display: The central area contains a visual representation of a unit (in this case, a cow), alongside numerical indicators showing the unit's relevant attributes: a health value (14) and a resource quantity (150 meat).
Garrison Section: This area is designated for unit management. It's marked clearly with the label "Garrison," indicating its function related to unit storage or tactical deployment.
Action Buttons: To the right, a series of action buttons facilitate interaction with the unit:
- Place: This checkbox suggests an option to deploy the unit in a specific location.
- Delete: This button allows for the removal of the unit from play.
- Move: This enables relocation of the unit on the game map.
- Rotate: A function for changing the unit's orientation, likely affecting its facing direction.
- Select: This may be used to choose the unit for further actions.
- Convert: Implies a function to change the unit’s allegiance or type.
Garrison Delete Button: Located at the bottom, this prominent button likely serves to remove the unit specifically from a garrisoned state.
