feat: Add Integrations page with API token management

New Integrations page in Wild Central UI for managing API tokens.
Provides token display, copy, and rotation so Wild Cloud and other
services can easily retrieve their authentication credentials.

- GET /api/v1/integrations returns current API token
- POST /api/v1/integrations/api-token/rotate generates a new token
- Frontend with show/hide toggle, copy button, and usage instructions
- Added to sidebar navigation under Central section
