[Dashboard] Access Tokens Page

[gtsiolis]

Problem to solve

Currently, API Tokens are mixed with other user settings like Environment Variables, Notifications, etc.

This is part of #3300. 🍕

User Experience goal

The user should be able to create and delete API Tokens for their account.

Proposal

In this first MVC (minimum viable change), we can do the following:

1. Introduce a dedicated page for creating and deleting API Tokens.
2. Rename API Tokens to Access Tokens to make it friendlier to the user but also clarify these are Personal Access Tokens (PATs). /cc @AlexTugarev
3. Show a modal dialog to prompt the user for a token name.
4. Once the token is generated provided a button to copy the token to clipboard.
5. Allow users to delete generated tokens from the tokens list.

Components involved:

1. Text Field
2. Button
3. Modal
