feat: keep AI vehicle labels visible in 'players' name mode

[fank]

Summary

User feedback:

It would be nice if AI's vehicle types would be visible at all times without having to have all AI's names (which cause clutter) visible. Very rarely you really care about individual AI's names, but you do care about type of vehicle they're driving.

In players mode the map now shows vehicle labels (e.g. "T-72 (3)") regardless of crew, while AI infantry names stay hidden. The none mode still hides everything, so the existing "hide all labels" escape hatch is preserved.

Behaviour matrix

nameMode	Player infantry	AI infantry	Player vehicle	AI vehicle
all	shown	shown	shown	shown
players	shown	hidden	shown	shown (was hidden)
none	hidden	hidden	hidden	hidden

Applies to both the canvas renderer (default) and the DOM Leaflet renderer (?renderer=dom fallback).

Test plan

• npm test (1497 tests, includes 2 new ones for the players-mode vehicle case and the none suppression case)
• tsc --noEmit clean
• Manually verify on a recording with mixed AI/player crews that AI vehicle labels appear in players mode and disappear in none mode

Code Review

This pull request modifies the Leaflet renderer to keep vehicle type labels and popups visible when the name display mode is set to 'players', including for AI-controlled vehicles. This allows for vehicle identification without showing names for all AI infantry. The changes include updates to the label drawing logic, the InternalMarkerHandle interface, and popup visibility checks, along with new unit tests. A review comment suggests refactoring a long object initialization for better readability.
