feat(i18n): translate five more systems

- Settings > Voice: video — preview, permission states, camera picker.
    This closes the Voice & Video tab; input, output and video are all done.
  - Create channel / category / space
  - Group DMs — new DM, add friends, group settings, leave
  - Join a space — discovery, invite code, and both federated auth phases
  - Delete account, transfer ownership, and the top-level error screen

Three patterns worth noting. Strings that are chosen in a helper or held in
state (the camera's hard-blocked copy, its preview errors, the space
visibility options, the invite failure reasons) now travel as translation
keys and are resolved where they render, so switching language re-labels
what is already on screen. Sentences that wrap an emphasised literal — the
host name when joining, the space and member names when transferring — are
split around their placeholder instead of interpolated, leaving word order
to the translation. And `CreateChannel` mapped over `(t) =>` for the channel
type, which shadowed the translator; the loop variable is now `channelType`.

The error boundary in main.tsx is a class component, so it reads the locale
once per render via `translate` rather than the hook — correct here anyway,
since an error screen has no reason to re-render on a language switch.

Two GroupDmSettings tests located the name input by its aria-label, which
this change translates. They now use the `data-group-dm-name-input`
attribute the input already carries, matching how the rest of that file
locates elements — and no longer break when copy changes.

Dictionary is at 595 keys, en and pt-BR at exact parity.

Verified: web build (tsc + vite), 490 web tests.
