Access Token Post Release Cleanup

[shrunyan]

• the empty token name & role experience should be clearer. Show an error explaining they are required. Do not open modal.
• Node SDK should be using the url component to get consistent styling.
• Token should be selectable text to allow for manual copying. Pasteboard functionality can be inconsistent across OS & Browsers. Relying on that is not good.
• Delete token button should be styled as a red delete button. See how domains is doing it.
• Create token button is extending past the card padding. Makes the layout inconsistent in comparison to other cards
• atom IDE text should link to https://zesty.org/tools/atom-package

• link the "access token" text in the description to https://zesty.org/apis/auth-api#token-based-authentication
• constrain modal width to a reasonable size
