No Play Button

Title:
Play button missing / EmulatorJS games fail to start on fresh Docker install

Body:

Hello,

I installed RomM with Docker on Ubuntu 24.04 using the official docker-compose example.

Everything else seems to work correctly:

• ROM scanning works
• ROMs appear in the library
• ScreenScraper metadata works
• EmulatorJS is enabled

But games cannot be played.

Problems:

• many systems do not show a Play button
• some systems show the console launch option, but starting the game gives:
  "failed to start game"

Tested systems:

• NES
• Atari 2600
• Nintendo 64

I already tried:

• Chrome
• Firefox
• Incognito mode
• docker compose restart
• adding platform mappings in config.yml

Example config.yml:

emulatorjs:
  enabled: true

platforms:
  nes: nes
  n64: n64
  atari2600: atari2600
