feat(server): add stale presence monitoring

 - **Game tick**: `bun run payload game-tick` — a `bin` registered on `payload.config.ts`, NOT an npm script. It processes active shipments + fuel consumption, then `process.exit(0)`.
-- **Bin file logging**: all four bins (`game-tick`, `market-tick`, `mission-tick`, `generate-mission`) tee their logs to daily files `logs/<bin-key>/<YYYY-MM-DD>.log` (UTC) via `createBinLogger` in `src/scripts/lib/binFileLogger.ts` — in addition to the console. Writes are `appendFileSync` (bin scripts `process.exit` immediately, so async streams would truncate). A fatal error in a bin is caught, logged to the file, and exits code 1. Directory override: `BIN_LOG_DIR` env (defaults to `<cwd>/logs` — inside Docker point it at a persistent volume). `logs/` is gitignored.
+- **Bin file logging**: all five bins (`game-tick`, `market-tick`, `mission-tick`, `server-tick`, `generate-mission`) tee their logs to daily files `logs/<bin-key>/<YYYY-MM-DD>.log` (UTC) via `createBinLogger` in `src/scripts/lib/binFileLogger.ts` — in addition to the console.

Directory override: `BIN_LOG_DIR` env (defaults to `<cwd>/logs` — inside Docker point it at a persistent volume). `logs/` is gitignored.
 - **Mission auto-completion**: `bun run payload mission-tick` — bin registered like the others (needs external cron). Sweeps missions whose status is `Scheduled`/`Active` and whose scheduled date (`classification.startDateTime`) has fully passed — from the start of the following **server-local** day — and sets them to `Completed`, emitting a `mission:auto-complete` event per mission (logic: `src/lib/intelligence/missionLifecycle.ts`, test: `tests/int/mission-lifecycle.int.spec.ts`). Draft statuses (Concept/Planning/Ready) and terminal statuses (Completed/Cancelled) are never touched; idempotent. Notifies clients via the same SSE path as the other ticks.
+- **Server presence**: `bun run payload server-tick` — bin registered like the others (needs external cron, every minute). Flips `game-servers` docs that claim `status: "online"` but whose last heartbeat (`lastSeenAt`) is older than 180s to `offline`, including online docs with no `lastSeenAt` at all; emits a `server:offline` event per flipped server (logic: `src/lib/arma-bridge/presence.ts`, test: `tests/int/server-presence.int.spec.ts`). Idempotent. Notifies clients via the same SSE path as the other ticks.
 - **Arrival handling** (`src/scripts/processShipmentTick.ts`): destination storage rules are re-checked on arrival; rejected cargo bounces back to origin, shipment goes `failed`, `ShipmentFail` event logged.
 - **GameRules tuning**: `proximityThreshold` and `gameTickIntervalMinutes` live on the global `game-rules` doc.
 - **UI**: `src/app/(frontend)/logistics/shipments/` (list + `[id]` detail with `ShipmentActions` controls), `src/app/(frontend)/logistics/game-vehicles/` (deployed vehicle views).

 For an Arma 3 unit deployment we self-host on **Coolify** with one container per environment (dev / stg / prod), a Coolify-managed PostgreSQL service per environment, a persistent volume for `/app/media`, and `docker exec` scheduled jobs for the game tick. The Dockerfile is Bun-based (multi-stage, Next.js standalone runtime + Payload CLI kept at runtime), and `docker-compose.yml` mirrors the same shape for local full-stack dev.
