fix: LND UI CSS, QR codes, services tab, wallet creation, tx filtering

- LND UI: replace cdn.tailwindcss.com with local tailwind.css (CSP fix)
- LND UI: make asset paths relative for nginx proxy compatibility
- Web5 wallet: add QR code for on-chain receive addresses (qrcode npm)
- Web5 wallet: hide incoming transactions after 3 confirmations
- Apps: add "Services" tab to separate backend containers from user apps
- Home: null guard on packages.value to prevent TypeError on load
- First-boot: auto-create Bitcoin Knots wallet (no longer auto-created)
- AppSession: add mempool-electrs to port mapping
