fix: add timeout to sticky privacy warnings in profile modal

Updates the privacy warning notifications in `ProfileModalController` to auto-dismiss after 5 seconds. This resolves an issue where warnings about direct message relays and NIP-17 delivery would persist indefinitely, requiring manual dismissal or page reload.

The fix applies `{ autoHideMs: 5000 }` to `this.showStatus` calls for:
- "Privacy warning: direct messages are using your default relays because no NIP-17 relay list is available."
- "Privacy warning: this recipient has not shared NIP-17 relays, so we'll use your default relays."
- "Privacy warning: this message used default relays because no NIP-17 relay list was found."
