chore(deps): bump antd to 6.5 and migrate deprecated component props

Upgrade frontend deps (antd 6.4.5 -> 6.5.0, Ant Design icons, TanStack
Query, i18next, eslint) and fasthttp 1.71 -> 1.72.

AntD 6.5 deprecated several Input/Card/Space props, so adapt the panel UI:
- Input/InputNumber addonBefore/addonAfter -> prefix/suffix
- Card bordered -> variant="outlined"
- Space direction -> orientation
- swap the hand-rolled Telegram SVG for the new TelegramFilled icon
- guard SettingListItem against cloning aria-labelledby onto a Fragment,
  which only accepts key/children
