chore: fix linter

[fortuna]

Summary:

• add targeted ESLint overrides for JS config/build files outside TS project coverage
• keep type-aware linting for in-project files
• include server_manager/www/app.spec.ts in server_manager/tsconfig.json

We can now call npm run lint:gts and npm run format:all from macOS, which is helpful for AI.

Validation:

• npm run action server_manager/electron/build -- --buildMode=debug
• npm run action server_manager/test
• npx eslint server_manager/www/app.spec.ts
• npx tsc -p server_manager/tsconfig.json --noEmit

Pull request overview

This PR fixes linter configuration to enable npm run lint:gts on macOS by properly handling JavaScript config/build files that are outside TypeScript project coverage. The changes remove the exclusion of app.spec.ts from the server_manager TypeScript project and add ESLint overrides to disable type-aware linting for JavaScript configuration files.

Changes:

• Added ESLint overrides for JavaScript config/build files not covered by TypeScript projects
• Removed exclusion of server_manager/www/app.spec.ts from server_manager/tsconfig.json
• Removed macOS-specific warnings from npm scripts in package.json
