feat(model+ui): F8-05 — race on OtherGroup, real attribution + N×M label

Issue #48 п.32 ("Stationed ship groups") shipped with a fragile race
fallback: when a foreign group sat on a non-`other`-kind planet the
inspector printed a generic "foreign" label, which collapsed the
race dropdown to a single uninformative bucket. The engine FBS
contract did not carry per-group race either, so live games hit the
same gap. This patch carries race authoritatively from the engine
through every layer down to the inspector.

Wire format & engine
- `pkg/schema/fbs/report.fbs`: add `race:string` to `OtherGroup` and
  `LocalGroup` (additive — old clients ignore).
- `pkg/schema/fbs/report/`: regenerated Go bindings.
- `ui/frontend/src/proto/galaxy/fbs/report/`: regenerated TS bindings.
- `pkg/model/report.OtherGroup.Race`: new field; carried through
  `LocalGroup` via the embedded `OtherGroup`.
- `pkg/transcoder/report.go`: encode + decode `race` on both
  `LocalGroup` and `OtherGroup`.
- `game/internal/controller/report.go.otherGroup`: set `v.Race`
  from `c.g.Race[c.RaceIndex(sg.OwnerID)].Name` so every emitted
  group — own or foreign — carries the resolved race name.

Legacy parser
- `tools/local-dev/legacy-report/parser.go`: capture the
  `<Race> Groups` header into `pendingOtherGroup.race`, fill local
  group `Race` from `p.rep.Race`, propagate both into the
  `report.OtherGroup` rows.
- Tests + smoke counts updated; regenerated `KNNTS{039,041}.json`
  fixtures so the synthetic loader carries the new field.

UI
- `ui/frontend/src/api/`: `ReportShipGroupBase.race` field;
  synthetic loader + FBS decoder populate it.
- `ui/frontend/src/lib/inspectors/planet/ship-groups.svelte`: the
  stationed-groups inspector picks race directly from
  `group.race` (own falls back to `localRace`, both finally to the
  `race.unknown` placeholder). The planet-owner / "foreign"
  heuristic is gone.
- Row label changes from "N ships mass M" to a compact
  `<class>` | `<N ×>` | `<mass>` three-column layout: the count
  cell is right-aligned tabular, the mass cell is right-aligned
  monospace + tabular, matching the inspector / calculator number
  conventions. Stale i18n keys removed
  (`ship_groups.row.count`, `.row.mass`, `.race.foreign`).
- All affected unit tests (8 files) carry the new `race` field.
