Addon Test: Adjust file exports to be ESM/CJS compatible

[valentinpalkovic]

What I did

Several plain JS files at the root of the test addon were pointing at nonexistent/incorrect dist files. Also, preset.js was overriding the exports set in src/preset.ts causing the serverChannel to be missing.

Greptile Summary

Updates addon-test module exports to support dual ESM/CJS compatibility by adding .mjs files and restructuring existing module exports.

• Added code/addons/test/manager.mjs, postinstall.mjs, and preset.mjs for ESM support
• Modified code/addons/test/manager.js and preset.js to use CommonJS require syntax
• Removed redundant code/addons/test/postinstall.cjs and preset.cjs files
• Simplified preset exports by removing explicit previewAnnotations implementation in favor of dist directory exports
