[dataquery + login] Translate Terms of Use menu label and popup text

[arnav-makkar]

Brief summary of changes

• Updated shared policy rendering so Terms of Use is localized consistently across both login and dataquery views.
• Refactored PolicyButton to use withTranslation('loris') and literal t(...) msgids for default policy entries (dataquery_example, login_example).
• Added translation coverage for the policy nav label, popup title, popup body, and accept/decline button text.
• Preserved safe fallback behavior: unmapped policy names/fields continue to display backend-provided text unchanged.
• Added translation entries for all supported UI languages (en, fr, ja, hi, es).

I do not have experience with Spanish or Japanese, so a strict review will be required for these translations.
Please let me know whatever changes required, and I'll be happy to incorporate them!

Unfortunately I think this needs to be redone -- For DB translations, we are creating pot files named after the DB Table such as Project in #10466, and then getting the values for that DB translation such as in #10462 where we get them from the Project pot for the Project table.

However, for a table like policies, we should copy the Config settings translations like in #9994

Closing this since it was done in #10513
