Summary

This PR adds Persian (fa) language support to the project.

A new fa locale has been introduced to improve accessibility for Persian-speaking users, especially those in Iran and Persian-speaking communities.

Scope of Changes

• Added Persian (fa) translation files
• Verified that the application can correctly load the new locale
• No changes to application logic or UI behavior

Notes

• Persian (فارسی) is a right-to-left (RTL) language.
  This PR focuses on language support only and does not introduce layout or RTL-specific UI changes.
• The translation is based on the existing English locale and follows the same structure.

Motivation

I have an academic and practical background in computer vision and AI applications, and I am actively involved in extending this project with features commonly required in real-world workflows.

Adding Persian language support helps broaden the accessibility of the project and supports contributors and users from Persian-speaking regions.

This work is supported by the Communication and Information Security Laboratory,
School of Electronic and Computer Engineering, Peking University.
