Pillar pages (internal)

This is an internal release to support our external marketing tasks 😉

• Added Pillar Pages section in profile sidebar
• Added Listing page of all available pillar pages, with actions like view draft/live, publish, remove, fork, edit, and add new pillar page.
• Add/Edit pillar page drawer contains the feature to add/edit new components to the page and option to preview the page without actually saving it

Apart from the above, following things have been taken care of

• While adding a new page, the slug should be unique.
• Added asset management section in profile sidebar
• Listing page where all available assets are displayed with the date of creation, name, and a small thumbnail of the image
• Option to view the image, copy the image URL and remove asset has been added
• A button for adding a new asset that opens a modal for adding a name and upload the image
• The live pillar pages will be visible at the slug given while creation, and for the preview page a preview route has been created which takes the slug and the preview token to display the data.
