fix: update GitHub Actions workflows and add Kurdish translation

- Update deprecated actions:
  - actions/checkout@v2 -> v4
  - actions-rs/toolchain@v1 -> dtolnay/rust-toolchain@stable
  - peter-evans/find-comment@v2 -> v3
  - tibdex/github-app-token@v1 -> v2
  - peter-evans/repository-dispatch@v2 -> v3

- Temporarily disable appium-mobile-tests trigger (PAT_TOKEN needs workflow scope)

- Add Kurdish (Kurmancî) translation (values-ku/strings.xml)
  - 1996 strings translated from English
  - Key UI terms in Kurdish (Wallet=Cîzdan, Account=Hesab, etc.)

- Update Pezkuwi branding images
