kevin 4b82340a9f fix: dynamic firewall config + UFW support + anti-spoof bug fix ...

Root cause: UFW FORWARD policy DROP overrides lmvpn_nat accept rules.
DNS (small UDP) worked but TCP packets were silently dropped.

- Add firewall_linux.go: dynamic NAT/forward/UFW config from ApplySettings
- Add firewall_darwin.go/firewall_other.go: stubs
- Fix anti-spoof bug in switch.go: return dropPacket sentinel instead of
  nil, so spoofed packets are no longer written to TUN
- Simplify install_linux.sh: remove hardcoded subnets and NAT config
- Add UFW detection to diag panel
