Color nuke telegraph circles by launcher relation (self/ally/enemy)

The blast-radius warning circle was always red, so players couldn't
tell who launched an incoming nuke. Now it's green for your own
nukes, yellow for ally/teammate nukes, and red for everyone else's.

Each telegraph carries a relation (0=self, 1=friendly, 2=enemy),
classified from the per-tick relation matrix — the same friend/foe
logic alt-view uses — and passed to the shader as a per-instance
attribute. Replay/spectator mode (no local player) stays all red.
Colors are tunable via the nukeTelegraph slice in render-settings.json.
