manueljpconde drags the rest of Mike into five languages

An earlier effort had taught Mike to speak English, Portuguese, Spanish, French and German, but several high-traffic screens were still stuck in hardcoded English. manueljpconde works through the ones that matter day to day: account and settings pages, the chat input, model controls, document upload, and the sidebar. A language picker now lives in the account profile, right under your email, so switching is a settings choice rather than a hunt. A few of the newest labels don't have translations in every language yet; those quietly fall back to English instead of breaking.

Tucked inside the same work is an unrelated fix worth knowing about: editing your display name or organisation now actually saves to the server. Before, the change only updated on your screen and vanished on reload. If you're sizing up this fork, that fix stands on its own and deserves a separate look.
