feat(rust): Dynamic PVP's zones on the feed and the map (PLAN_REDESIGNS §14.3.3)

Stage 4 of the §14.3 integration plan, on protocol 14 (docs
rust-link/PROTOCOL.md §20.7).

- pvp.zone.created is a public kind, pvp.zone.deleted a staff kind. Each row
  is read per viewer by the new dynamicPvp.js: grid for everyone, the event's
  name only for Dynamic PVP's own vanilla events, position and zone id for
  staff only.
- The feed's world filter carries the opening: "A PvP zone opened around the
  downed patrol helicopter · G7 · for 10 min". It names nobody.
- The map gains a fifth layer, `pvp` (PvP zones), public by default with its
  own audience in Admin → Rust visibility, drawn as a red ring with its
  event's name.
- Server settings' plugin line names Dynamic PVP; the swagger schemas and
  route descriptions carry the layer and the integration (fragment
  regenerated); ci/bundle.json ships dynamicPvp.js; README lists it.

Tests: server 611/611 (dynamicPvp.test.js new, catalogue and map extended)
and every check; client 89/89 (feed and map tooltip), build and externals.
