SPK daemon fixes (x5925 testing feedback):
- register_with_hub: added --max-time 15 to prevent indefinite hang
- Removed bash 'local' keyword for busybox ash compatibility
- postinst: mkdir -p /usr/local/bin before copying Tailscale binaries
- postinst: chmod +x all bin/*.sh (fixes 644 execute bit bug)
- Added x5925-boot.sh for reboot persistence (stopgap until daemon fixed)
Hub security hardening:
- Added POST /api/authorize-key endpoint with device_id + pubkey
- Keys auto-authorized with restrict,port-forwarding,permitlisten="<port>"
- No shell access allowed — only tunnel forwarding to assigned port
- Server.py updated with input validation on key format
- register.sh --authorize-key subcommand for secure key management
GL daemon: same --max-time fix applied for curl timeout

- Bundled tailscale 1.98.9 + tailscaled ARMv7 (ELF 32-bit, statically linked)
- Fixed connect-daemon.sh 644 → 755 (was preventing daemon from starting)
- Postinst now chmod +x all bin/*.sh and bundled binaries
- Postinst copies tailscale/tailscaled to /usr/local/bin if not present
- Hub firewall: opened ports 8080 (API) and 2230-2299 (SSH tunnels)
- Hub systemd service restarted after firewall fix
