feat(rust): NPC profiles and placements pages, the profile leaderboard (runicnpc stage 4)

Admin: Rust NPC profiles (the form RunicNPC reads, per server, shared or
fleet, each server's push state and refusals, replaced profiles with
Restore) and Rust NPC placements (the live map: click to place, pins for
every placement; edit, rename, respawn, remove). The live map takes a pick
handler and pins, unchanged for the public page.

Public: the leaderboard ranks by a profile's kills (D250), and opening a
row shows that player's kills by profile (D252); the killfeed names a
RunicNPC NPC by its own name. Player: your own kills by profile. Titles: a
rule on a profile's kills picks the profile. npcs.test.js covers the
profile checks, adoption, the push, the picker and verb, the triggers, kill
crediting, titles and placements (481 server tests).
