fix: MSDOS games fail to launch in console mode ("Error for site owner / Check console")

[Copilot]

dosbox_pure (MSDOS) requires SharedArrayBuffer for multi-threading, which browsers gate behind Cross-Origin Isolation (COEP: require-corp + COOP: same-origin). The nginx COEP/COOP maps only matched /rom/.*/ejs (normal player), leaving the console play path /console/rom/[0-9]+/play without those headers. Combined with the console Game.vue using SPA navigation without a subsequent hard reload, the emulator never received a cross-origin isolated context and failed immediately.

Changes

• docker/nginx/templates/default.conf.template — extend COEP/COOP header maps to also match /console/rom/[0-9]+/play:

  map $request_uri $coep_header {
      default        "";
      ~^/rom/.*/ejs$ "require-corp";
      ~^/console/rom/[0-9]+/play "require-corp";   # added
  }

• frontend/src/console/views/Game.vue — make play() async, await router.push(…), then call router.go(0) to force a full HTTP request so nginx delivers the isolation headers. Mirrors the identical pattern already used in PlayBtn.vue.

• frontend/src/console/views/Play.vue — add onUnmounted(() => window.location.reload()) to drop the cross-origin isolated context when the game session ends. Mirrors the identical teardown already in the normal Player.vue.

Pull request overview

Fixes MSDOS (dosbox_pure) launch failures in console mode by ensuring the /console/rom/:rom/play route runs in a cross-origin isolated context (COEP/COOP headers) and by forcing hard reloads so the browser actually receives (and later drops) those headers.

Changes:

• Extend nginx COEP/COOP header maps to include /console/rom/[0-9]+/play.
• In console Game.vue, force a full reload after navigating to the play route so the response includes isolation headers.
• In console Play.vue, force a full reload on unmount to exit cross-origin isolation after the session ends.

play() now forces a full page reload via router.go(0). Because romApi.updateUserRomProps(..., updateLastPlayed: true) is currently fire-and-forget, the pending PUT can be aborted by the reload, so last_played may not get updated reliably. Consider awaiting that request (or sending it via a keepalive/beacon-style call) before triggering the reload.

The new map $request_uri regex for /console/rom/[0-9]+/play isn’t anchored, so it will also match unintended prefixes (e.g. /console/rom/123/playground). Consider tightening it to only match the exact play route (optionally allowing query strings), e.g. ^/console/rom/[0-9]+/play(?:$|\?).
