fix: Multiple bug fixes and code cleanup

- package.json: Add missing @eslint/js and globals devDependencies
- docker-entrypoint.sh: Fix X11 lock file name (.X1-lock → .X11-lock)
- epic-claimer-new.js: Use imported solveCloudflare/isCloudflareChallenge instead of duplicate implementations
- src/cloudflare.js: Fix solveCloudflare to use cfg.flaresolverr_url, remove unused imports
- epic-games.js: Remove unused code (getFreeGamesFromGraphQL, exchangeTokenForCookies, FREE_GAMES_QUERY, deviceAuthLoginSuccess variable)
- Run eslint --fix to clean up trailing spaces
