Evan b4a14f9b9d Move attack troop overlay to WebGL (#3996)
## Description:

Replaces the DOM-based `AttackingTroopsOverlay` with
`AttackingTroopsController`, rendering attack troop counts through
`WorldTextPass` instead of a separate fixed-position DOM container.

## Summary

- New `AttackingTroopsController` polls `attackClusteredPositions()`
every 200ms and pushes labels to the WebGL view each frame, lerping
cluster positions over 250ms for smooth front-line movement (replaces
the old CSS `transform 0.25s` transition).
- `WorldTextPass` gains `setAttackTroopLabels()` and renders them at a
fixed on-screen size (zoom-independent) using `screenScale / zoom`.
- World text now draws on top of `NamePass` so attack callouts aren't
hidden behind centered player names.
- Fragment shader adds a soft quadratic dark halo around every
world-text label; extent uses the remaining SDF range after the hard
outline so it fades smoothly to zero (no rectangular clipping).
- Deletes `AttackingTroopsOverlay.ts`; existing unit tests repointed to
the controller's exported `alignClusterOrder`.
