fix missing foreign language characters, block translation popup (#88)

before:

<img width="1924" height="1087" alt="image"
src="https://github.com/user-attachments/assets/da6de497-5d63-46d7-b38c-c2f0011ce39e"
/>

after:

<img width="1921" height="1082" alt="image"
src="https://github.com/user-attachments/assets/3499d10b-d8da-4948-8659-92c9926d7da2"
/>

also applied the same policy file to the headless image. Tested this
with a vibed up playwright script that connected to the headless image
and took a screenshot of coupang.com
