Adds the Races View in the in-game shell. The table lists every
non-extinct other race with tech levels (percent), totals,
planets, votes received, and a per-row WAR | PEACE segmented
control. A single vote-recipient slot above the table queues a
`CommandRaceVote`; per-row buttons queue `CommandRaceRelation`.
Both commands flow through the existing order draft store with
collapse-by-acceptor (stance) and singleton (vote) rules.
`GameReport` widens with `races`, `myVotes`, `myVoteFor`; the
decoder walks `report.player[]` once for the richer projection.
The optimistic overlay flips stance and vote target immediately;
`votesReceived`, `myVotes`, and the alliance summary stay
server-authoritative — alliance grouping and the 2/3 victory
check are tallied on the server at turn cutoff and explicitly
not surfaced client-side (`rules.txt` keeps foreign races'
outgoing vote targets private).
Includes Vitest component coverage of stance and vote
collapse rules + a Playwright e2e that drives both commands
through the dispatcher route and verifies the gateway saw the
expected `CommandRaceRelation` / `CommandRaceVote` payloads.
