feat(rust): the live map (phase 14, protocol 11)

PLAN.md §30 as approved, plus D119/D120 from the build.

Server:
- rust_map_images (one row per server: picture as MEDIUMBLOB, geometry,
  monuments, DERIVATION_VERSION) and rust_map_overrides; purge.sql pair.
- mapImages.js: D110. The board poll notices a new boot/wipe/seed/size and
  asks map.info; a new key or hash from the free Rust+ cache (or a render
  kept on disk) is fetched in slices, checked against its SHA-256 and stored
  in one statement. One fetch per server, a backoff on failure, `stale`
  abandons a fetch that straddles a map change. Render now (D109) is
  admin-only and watched to completion.
- mapLive.js: D111. One map.live per server per 5 s whoever asks; positions
  are held in memory only.
- model/map: four layers (world, events public; players, bases staff), a
  fleet default plus per-server override (D114), the players layer capped by
  presence (D113), own dot and online first-party clan mates for a linked
  viewer (D115, D117, D118). A layer the viewer may not see is absent from
  the answer, never sent and hidden.
- Routes: public /servers/:id/map, /map/image (immutable under its hash),
  /map/live; admin /servers/:id/map/fetch and /render; the Map card on the
  visibility PUT. Swagger fragment and frozen manifest regenerated.

Client:
- A Map tab: Leaflet over the picture in CRS.Simple, the game's own grid
  (labels only when a cell is wide enough to hold one), a legend that lists
  hidden layers with who can see them, polled every 10 s while visible.
- D120: Leaflet is a lazy split chunk beside entry.js, not in it. release.yml
  copies every dist/*.js; checkExternals and build.test.js hold both ends.
- The Map card on Admin -> Rust visibility, with Fetch again and Render now.

Capability `map` declared for the Android app (phase 15).
