feat(rust): RaidableBases — feed, raids map layer, Warlord, Spawn a raid base, profiles (PLAN_REDESIGNS §11.4)

PLAN_REDESIGNS §11.4 (D202-D208, D386-D391), protocol 14. Spec: docs
rust-link/PROTOCOL.md §20.12.

- raid.started, raid.completed, raid.purchased and raid.locked public,
  raid.ended staff's; raidableBases.js reads each row per viewer (raiders'
  and a buyer's names only for the presence audience, D376/D390; Steam ids,
  position and a run's key only for staff). Feed lines in the World filter.
- The step rust.raidbase.spawn, "Spawn a raid base" (ledgered, budget
  rust.raids): difficulty, profile and base from option sources listing each
  server's own names (D386), a spot as a world call's location with a height
  adjustment or an exact height, and PvP/NPCs/lock as on/off/blank. A base
  the raids helper made is a world resource, so eventWorld's revert and
  reconcile serve it and world.expired marks it expired; one it did not make
  records nothing and the run log says it despawns on its own timer. Refused
  at verify for a server that said it cannot; a dry run with a spot returns
  the spot check as detail.warnings (MODULE_API 1.16.0, D391). rb-not-ready
  retries in ten minutes.
- Warlord: raids_completed, title category raidscompleted, the leaderboard's
  Raid bases column (sort=raidsCompleted).
- The map's raids layer (D114), public by default with its own audience; the
  run's key is dropped before any viewer gets it.
- Server settings' line for RaidableBases; its profiles in Mod configuration
  under a virtual path (D205).
- Swagger fragment, bundle and README.

Tests: server 684/684 (raidableBases.test.js new, every name in it invented);
client 99/99, build and externals.
