Two issues surfaced once the long-lived dev environment finally
reached the diplomail view:
1. `/sent` returns one row per recipient for broadcast and admin
fan-outs (so the admin tooling can render the materialised
audience). The list pane fed all rows into the stand-alone
bucket, so the `{#each entries as e (entryKey(e))}` key in
`thread-list.svelte` collapsed to the same `standalone:${id}`
for every recipient and Svelte 5 aborted the render with
`each_key_duplicate`. Dedupe stand-alones by `message_id` in
`buildEntries`.
2. The compose dialog exposed an `admin` kind toggle gated on
"owner of game". That was a Phase 28 plan decision, but admin
compose is an operator tool (server admin), not an in-game
action — every game owner should not be able to broadcast
admin notifications. Drop the admin option, the audience
sub-toggles, and the admin path through `submit`. The
`MailStore.composeAdmin` wrapper and the backend RPC stay so
the future admin UI can call them.
Vitest covers the fan-out dedup with three rows sharing one
`message_id` collapsing to a single stand-alone entry.

Adds `src/lib/mail-store.svelte.ts` — the reactive store that
coordinates the in-game mail view. Responsibilities:
- holds the inbox and sent listings for the current game and fires
the initial parallel fetch (`fetchInbox` + `fetchSent`) on
`setGame`;
- exposes a `entries` derived rune that builds the unified list
pane: per-race threads merged from incoming + outgoing personal
messages, plus stand-alone items for system / admin / own
paid-tier broadcasts. Thread messages are sorted oldest → newest
for chat-style rendering; the list itself sorts newest-first by
the most-recent entry timestamp;
- derives `unreadCount` from `readAt === null` rows for the header
view-menu badge;
- imperative `markRead` / `softDelete` actions with optimistic
state flips and roll-back on RPC failure;
- compose actions for personal / paid-tier broadcast / owner-admin
sends;
- `applyPushEvent(gameId)` hook called by the layout when a
`diplomail.message.received` push frame arrives; refetches the
inbox without trusting the preview payload;
- persists the most recent message id under
`cache.diplomail/${gameId}/last-seen` so a returning session can
pre-paint the badge without a network round-trip.
