A multilingual site, a live team page, and a cleaner feel

A big round of front-end work, plus quieter upgrades under the hood.

- The whole site now speaks English, German, and Russian, with real `/de` and
`/ru` links and matching SEO tags so each language gets found on its own.
- The team page updates itself. Names, avatars, and banners come straight from
Discord, so it is always current without us editing anything.
- The pricing card is sharp again, the hero fills the screen, and clicking a menu
item now scrolls cleanly to the right section.
- Refreshed the blog and added a new guide for anyone looking for a custom Discord
bot or a custom website.
- Plenty of behind-the-scenes bot work too: smarter tickets, a feedback request
when a project ships, and cleaner notifications.
