🚀 Enhancement: Create console users/members as owner

### 🔖 Enhancement description

Add the ability to create a console account when logged in as owner, in addition to sending an invite.

### 🎤 Pitch

If you have SMTP disabled you can't invite new members (you get the error `SMTP is disabled on your Appwrite instance`). Making it possible to create a new account as owner would help.

Alternatively, generate an invite link that you can share with someone that makes it possible for them to register, even if you have `_APP_CONSOLE_WHITELIST_ROOT=enabled` and SMTP disabled.
