feat(i18n): integrate PermissionPrompt, fix hardcoded tips in SessionList and WelcomeScreen

- PermissionPrompt: fully i18n-ized (17 strings -> t() calls), new locale
  module ui-permission-prompt.json with en/zh-CN translations
- SessionList: fix 6 remaining hardcoded strings (delete confirm,
  footer help, waiting/denied statuses)
- WelcomeScreen: fix 'Tips:' hardcoded prefix -> t('ui.welcome.tipsPrefix')
- App.tsx: fix hardcoded permission denied status message
- locales: add 25 new translation keys across 4 modules (total 267 keys)
- docs: update i18n-todo.md with comprehensive scan results and
  new findings (PermissionPrompt, App.tsx, Tips component)
- settings.ts: fix indentation (tab to spaces)
