[PATCH manager v2] sdn: subnets: hide irrelevant fields depending on zone type

[Theodor Fumics]

The SNAT option is only applicable to Simple and EVPN zone types.
For other zone types, this field is irrelevant and can cause confusion.
This commit hides the SNAT field when it is not applicable to the
selected zone type, improving clarity for users.

    Changes from v1 -> v2
