feat(i18n): update Urdu localization with missing translations

[afaq-karim]

Description

• This PR updates the Urdu translation file (src/gui/src/i18n/translations/ur.js) by adding translations for keys that were previously undefined. The translations are aligned with the English text, culturally appropriate, and placeholders such as %strong% have been preserved and positioned correctly.

Changes

• Added translations for missing keys such as:
  "allow", "share_with", "unzipping", "Owner", etc.
• Ensured all %strong% placeholders are retained and properly placed in the Urdu context.
• Verified grammar, punctuation, and cultural nuances to maintain meaning and appropriateness.
• Updated comments to include the English equivalent for easier review.

This PR resolves #847 by adding missing Urdu translations for the localization file.
