Fix mini-map interaction, dragging/resizing and state reprojection logic

[Atothendrew]

Motivation

• The mini-map mishandled clicks by invoking delegate callbacks unconditionally instead of honoring the updatePositionOnClick flag.
• Runtime toggling of the base marker (showBaseMarker) did not create or remove the marker after initialization, causing inconsistencies when enabling/disabling it.
• Dragging, resizing and reprojection flows lost or misused state leading to incorrect coordinate math, stuck timeouts, and overlays that did not update after size changes.

Description

• Made baseMarker mutable and implemented a didSet flow on showBaseMarker to dynamically create/remove the marker and reproject its position using cached scene state via currentBasePosition and currentSceneSize.
• Guarded delegate invocation in handleClick(at:) so the delegate is only called when updatePositionOnClick is true.
• Added cached state properties currentBasePosition, currentCameraPosition, currentCameraZoom, and ensured updateBasePosition and updateCameraViewFrame update those caches for later reprojection.
• Hardened coordinate conversion (convertToMapPosition and convertFromMapPosition) to guard against zero-sized scene/map dimensions and allow conversions when the node is detached by using cached currentSceneSize.
• Fixed dragging math by storing the local drag offset at start and converting pointer locations into the parent coordinate space during updates, and initialized lastDragTime/lastResizeTime at operation start to avoid premature stuck resets.
• Made resizing stable: applied a safe zoom for camera viewport computation, corrected macOS Y-axis resize delta direction, and refreshed base marker, entities and camera frame after mapSize changes.

Testing

• Ran swift test in this environment which could not complete due to the platform missing the SpriteKit framework (error: no such module 'SpriteKit'), so unit tests could not be executed here.
• Changes were validated by static review and lightweight local execution where possible; logic and API behaviour were updated without modifying public method signatures.
