feat: add custom domain defaults, credential kid, and connection configuration

[fern-api]

🔧 Changes

Auto-generated SDK regeneration to match the latest Auth0 API definition. Key changes:

• Custom Domains: Add GetDefault and SetDefault endpoints for managing the tenant's default domain, along with new response types (GetDefaultDomainResponseContent, GetDefaultCanonicalDomainResponseContent, GetDefaultCustomDomainResponseContent, UpdateDefaultDomainResponseContent, UpdateDefaultCanonicalDomainResponseContent, UpdateDefaultCustomDomainResponseContent, SetDefaultCustomDomainRequestContent) and a new customdomains sub-package
• Clients: Add Kid (Key ID) field to PublicKeyCredential for uniquely identifying credentials
• Connections: Add Configuration field to ConnectionPropertiesOptions and UpdateConnectionOptions for encrypted string-only connection configurations
• Client Grants: Make ClientID optional on CreateClientGrantRequestContent; add q and clientID query parameters for advanced filtering
• Organization Discovery Domains: Add eventual consistency documentation to List, GetByName, and Get endpoints

⚠️ Breaking Changes

1. GetGroupResponseContent — Removed OrganizationID and Description fields

The OrganizationID and Description fields, along with their getters and setters, have been removed from GetGroupResponseContent. Group name uniqueness scope changed from "connection, organization, or tenant" to "connection".

Before:

group, _ := client.Groups.Get(ctx, groupID)
orgID := group.GetOrganizationID()   // worked
desc := group.GetDescription()       // worked

group.SetOrganizationID(&orgID)
group.SetDescription(&desc)

After:

group, _ := client.Groups.Get(ctx, groupID)
// group.GetOrganizationID()  — REMOVED, will not compile
// group.GetDescription()     — REMOVED, will not compile
// group.SetOrganizationID()  — REMOVED, will not compile
// group.SetDescription()     — REMOVED, will not compile

2. CreateClientGrantRequestContent — ClientID changed from required to optional

ClientID changed from string to *string, making it an optional field.

Before:

req := &management.CreateClientGrantRequestContent{
    ClientID: "my-client-id",       // string (required)
    Audience: "https://my-api.com",
}

After:

clientID := "my-client-id"
req := &management.CreateClientGrantRequestContent{
    ClientID: &clientID,             // *string (optional)
    Audience: "https://my-api.com",
}

3. UpdateCustomDomainResponseContent — Verification field changed from required to optional, OriginDomainName added

Before:

resp, _ := client.CustomDomains.Update(ctx, id, req)
v := resp.Verification  // type: DomainVerification (value type, always present)

After:

resp, _ := client.CustomDomains.Update(ctx, id, req)
v := resp.Verification           // type: *DomainVerification (pointer, may be nil)
origin := resp.OriginDomainName  // NEW: *string
if resp.Verification != nil {
    // safe to use
}
