feat(auth-files): add note field for individual credentials

- Add note field to the credential field editor (PrefixProxyEditorModal)
- Store note as a string in the credential JSON file
- Display note on AuthFileCard with 2-line clamp for long text
- Note is saved when non-empty, removed from JSON when cleared
- Add i18n translations for zh-CN, en, and ru
