Improve VPN ciphers
...
- Improve security by removing support for modp1536 (DH group 5),
which is less secure and rarely used by VPN clients. To do this,
we specify modp2048 on the "ike=" line in ipsec.conf.

Improve VPN ciphers
...
- Improve security by removing support for modp1024 (DH group 2),
which is less secure and no longer enabled in Libreswan by default.
- The native VPN client on Android devices uses modp1024 for the
IPsec/L2TP and IPsec/XAuth ("Cisco IPsec") modes. After this change,
Android users should instead connect using IKEv2 mode (recommended).

Improve IP check
...
- Instead of finding the server's public IP, use the IP address
on the default route if it is not a private IP. This makes VPN
setup slightly faster by skipping IP detection.
- Add a fallback URL for finding the server's public IP.

Add an option to skip IKEv2 setup
...
- Add an option to skip IKEv2 setup when installing the IPsec VPN.
Example: sudo VPN_SKIP_IKEV2=yes sh vpn.sh
- This allows users to set up an IKEv1-only VPN, or install IKEv2
interactively using "sudo ikev2.sh" after VPN setup.

Improve IPsec config
...
- IKEv2 mode uses retransmit-timeout instead of dpdtimeout.
- Increase timeouts from 120s to 300s, so that the VPN server can
keep the VPN connection open if the client's network is unstable.
