[Feature] Add option to disable email verification on registration

Bắt đầu với internal/schema/siteinfo_schema.go và theo dõi luồng đăng ký trong internal/service/content/user_service.go, sau đó kiểm tra internal/controller_admin/siteinfo_controller.go và các component quản trị bên dưới ui/src/admin/pages/site/. Chạy các test đăng ký và thông tin site hiện có nếu có. Công việc được hoàn tất khi setting được cung cấp và lưu bền vững, mặc định yêu cầu verification, thay đổi đúng trạng thái đăng ký và có thể được điều khiển từ admin panel.

Feature Request: Allow admin to disable email verification requirement

Problem

Currently, Apache Answer always requires email verification after registration. Users cannot access the platform until they click the verification link in their email.

This is problematic because:

• Many users don't receive or check the verification email
• It creates friction in user onboarding
• Some deployments (internal networks, dev environments) don't need email verification

Proposed Solution

Add an admin configuration option to allow users to use the platform immediately after registration without email verification.

Technical Changes Required

1. Schema Changes

File: internal/schema/siteinfo_schema.go

type SiteLoginReq struct {
    AllowNewRegistrations    bool     `json:"allow_new_registrations"`
    AllowEmailRegistrations bool     `json:"allow_email_registrations"`
    AllowPasswordLogin      bool     `json:"allow_password_login"`
    AllowEmailDomains       []string `json:"allow_email_domains"`
    RequireEmailVerification bool    `json:"require_email_verification"` // NEW
}

2. Registration Logic

File: internal/service/content/user_service.go

Current behavior (line ~471):

userInfo.MailStatus = entity.EmailStatusToBeVerified  // Always unverified

New behavior:

if requireEmailVerification {
    userInfo.MailStatus = entity.EmailStatusToBeVerified
} else {
    userInfo.MailStatus = entity.EmailStatusAvailable  // Verified immediately
}

3. Admin API

File: internal/controller_admin/siteinfo_controller.go

• Update SiteLoginReq struct to include new field
• Ensure admin can toggle this setting

4. Frontend Admin Panel

File: ui/src/admin/pages/site/ (or similar)

• Add toggle switch for "Require Email Verification" in login settings

Default Behavior

• RequireEmailVerification = true (maintain backward compatibility)
• Admin can set to false to allow immediate access after registration

Database Changes

None required - existing mail_status field already supports both states:

• 1 = EmailStatusAvailable (verified)
• 2 = EmailStatusToBeVerified (pending)

Testing Checklist

• New user registration with verification enabled → mail_status = 2
• New user registration with verification disabled → mail_status = 1
• Admin can toggle the setting via admin panel
• API returns correct value for require_email_verification
• Existing users with mail_status = 2 still need to verify (if required)
