feat(rust): bosses and passive NPCs on the profile form, and public boss triggers (runicnpc stage 6)

The profile form's boss box (D273-D277): the bar's distance, where its
lines are said, the spawn and death lines, and phases at health
percentages, each with optional damage, aim, speed, ranges, a kit swap,
adds of another profile and a line. The passive role (D278, D279,
D288): press E answers with a chat line or a window, it moves as its
profile says (now including `stand`), and it starts unhurtable.

The site checks both as RunicNPC does, in its words; a phase's kit is
checked on each server like the profile's own, and its adds must name a
site profile that is not a boss.

Public triggers rust.boss.spawned, rust.boss.phase and rust.boss.killed
(D277) from the bridge's new frames. In the feed, a boss appearing is
public; its death names the killer, so it sits behind the presence
setting; its phases are staff's, as the game tells them only to players
near it (D286). engagement-triggers.json regenerated.
