fix(i18n): keep locale on website->dashboard links; dashboard defaults to fa

Marketing-site login/register/dashboard links were locale-less (app.meezi.ir/login), so the dashboard auto-detected locale from the browser Accept-Language (en-US) and redirected Persian users to /en. Links now carry the current locale, and the dashboard sets localeDetection:false so any locale-less entry defaults to fa (Iran-first) instead of guessing from the browser.
