chore(extension): hardcode public key in manifest.json

[yury-s]

Summary

• Move extension public key directly into manifest.json instead of injecting it at build time
• Remove SET_EXTENSION_PUBLIC_KEY_IN_MANIFEST env var from build and CI
• Simplify extension test fixtures that no longer need to patch the key
