i18n: localize hardcoded UI strings across 10 components

Wraps the hardcoded strings flagged in LOTUS_BUGS.md (Localization rows)
in t() via react-i18next, and adds the keys to public/locales/en.json
under the existing Organisms.* namespace. de.json intentionally left to
fall back to en for now (fallbackLng: 'en') rather than fabricate
translations.

Files: CreateRoomTypeSelector, ImageViewer, MsgTypeRenderers (MLocation),
Reply (ThreadIndicator), ImageContent, DeviceVerification (5 subcomponents),
UrlPreviewCard (DiscordCard), InviteUserPrompt, UploadBoard, PasswordStage.
