This MR enables FreedomBox to connect as a "client" to a WireGuard
"server" using IPv6.
- Validate IPv4/6 with ip_interface
- Created helper functions to build NM settings for IPv4/6
- Modify get_settings to include settings for either IP version 4 or 6
- Created helper function to get NM address info
- Modify get_nm_info to work with IPv4 and IPv6
- Modified tests to use validate_ip_address_with_network
- Added IPv6 valid and invalid patterns to tests
Tested:
- IPv4 works unchanged
- IPv6 parsing + NM settings generation works
- IPv6 display in Show Server UI
Not tested:
- Needs IPv6 WireGuard server for full connectivity test
Closes: #1762

- Currently, the value is hard-coded as /24. Instead take this as input and use
that value.
Tests:
- Entering invalid IPv4 address results in 'Enter a valid IPv4 address' error
message during form submission.
- Entering invalid prefix such as /33 results in 'Enter a valid network prefix
or net mask.' error during form submission.
- Both /32 and /255.255.255.255 formats are accepted.
- The description text for the form field 'IP address' is as expected.
- Changing the value of default route and IP address + netmask reflects in the
status page. Correct values is shown in the edit server and server status page.
- Not providing a netmask results in /32 being assigned.
- Unit and functional tests for wireguard pass. There are some intermittent
failures with functional tests that are unrelated to the patch.
- Setting the /32 prefix results in correct routing table as shown by 'ip route
show table all'. No default routes are network routes are present. 'traceroute
1.1.1.1' shows route taken via regular network.
- Setting the /24 prefix results in correct routing table. No default routes are
present. However, for the /24 network a route is present with device wg1.
'traceroute 1.1.1.1' shows route taken via regular network.
- Enabling the default route results in correct routing table. Default route is
shown for device wg1 with high priority. 'traceroute 1.1.1.1' shows route taken
via WireGuard network.
