feat: bitcoin-ui CSS fix, HTTPS proxy support, deploy script improvements

Bitcoin UI:
- Replace cdn.tailwindcss.com with locally bundled tailwind.css (CSP blocks external scripts)
- Make all asset paths relative for nginx proxy compatibility
- Add bitcoin-ui build/deploy to deploy-to-target.sh (was missing entirely)
- Use --network host (bitcoin-ui proxies Bitcoin RPC at 127.0.0.1:8332)

HTTPS mixed content fix:
- Add HTTPS_PROXY_PATHS in AppSession.vue — when parent page is HTTPS,
  iframe loads through nginx proxy instead of direct HTTP port
- Prevents browser blocking HTTP iframes inside HTTPS pages
- All Tailscale servers use HTTPS, this was breaking all app iframes

Deploy & first-boot improvements:
- first-boot-containers.sh auto-detects disk size for pruning vs txindex
- first-boot-containers.sh checks fallback source path for UI containers
- Added mempool-electrs to APP_PORTS mapping
- ElectrumX container creation in first-boot
- Podman doctor/fix/uptime skills added

Also includes: session persistence, identity management, LND transactions,
ElectrumX status UI, nostr-provider improvements, Web5 enhancements
