feat(rust): RunicNPC profiles, their push and adoption, per-profile kills (runicnpc stage 4, WIP)

Schema for site NPC profiles (per server, shared or fleet), the per-server
push record, and kills by profile. The push adopts a server's own profiles
before its first push (D244), keeping one whose name a site profile already
has as replaced (D251). The tally's npcProfileKills are stored per profile
and credited to the site profile pushed under that name (D247).
