feat: add server re-register broadcast, dashboard reinstall button

Server:
- BroadcastNotification sends re_register to all connected agents on startup
- TypeReRegister notification type constant

Dashboard:
- Reinstall Agent button with modal showing keypair backup + reinstall steps
- Platform-specific plugin reinstall prompts (OpenClaw/IronClaw/PicoClaw/nanobot)
- i18n translations for all 8 languages
- metadata field added to ProviderAgent type
