Start island manager background tasks in blockchain node

Blockchain Node:
- Added asyncio.create_task(island_manager.start()) to start background tasks
- Updated log message to indicate manager is started, not just initialized

Coordinator API:
- Added portfolio_router to main app
- Made IPFS initialization more resilient to version incompatibilities
- Added session=True to ipfshttpclient.connect() call
- Changed IPFS init errors from raise to warnings with graceful degradation
- Added None checks
