add teammate pulse highlight during spawn phase in team games (#2768)

Adds a pulsing highlight effect for teammates during the spawn phase in
team games. This helps colorblind players identify their teammates on
the map more easily.

- Teammates show a subtle green/team-colored pulse (5-14px radius)
- Player's own pulse remains unchanged (8-24px white pulse)
- Only activates during spawn phase in team games
- Animation stays synchronized with player's own pulse

I didn't want to come empty handed with my request so I generated the
code
I do know python and a little rust, but don't have TypeScript experience
- I know you guys are probably getting flooded with AI slop so I hope
its okay.
Please implement the feature at the very least because its SO much
better not having to hunt around.
🤖 Generated with [Claude Code](https://claude.com/claude-code)

So the code calls drawTeammateHighlights() inside of
drawFocusedPlayerHighlight() so it can only occur where current
highlighting occurs
Then uses the existing isOnSameTeam() to find teammates
Then uses the existing drawBreathingRing() function 


- [x] I have added screenshots for all UI updates
I took a video since it best captures the feature
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
I'm not that good at coding formally, I tested it manually by loading
into team games, but I'm going to need help with the code being tested.
(Please help)
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
I did load into multiple lobbies and made sure the feature works, its a
really simple feature so I am confident there isn't any Lovecraftian bug
lurking in it. It also uses mostly existing functions and features
within the code base.
