Remove New Design Feature Flag

[jkachel]

Checklist of things to do when de-flagging the new design:

• Remove calls to is_enabled
• Specifically remove flagged block from cms/templates/product_page.html
• Remove catalog view

  mitxonline/main/views.py

  Line 43 in 0b6e49d

  def catalog(request, **kwargs):

  and update url path to reference index view.

Tabled:

• Clean up flagged CSS - remove CSS classes that are for the old design
• Audit static images included in the repository. I'm guessing that some of these are no longer used in the new design.

Notes about the CSS auditing: I de-new-designed the CSS and noted that there are some pages that still have old bits. Those are:

• Sign In - uses old fonts and background color
• Financial Assistance - uses old background and old footer
• Edit Profile - uses old fonts and background color
• Account - uses old fonts and background color
• Dashboard - uses old fonts and background color, cards need updating to look right
• Program Record - uses old fonts and background color
• Order History - uses old fonts and background color; table needs to be updated for new design

Some of these changes are pretty straightforward but some aren't. I did not modify the CSS classes that are being used in components and templates, so not modifying the CSS or images. I don't think the Figma design for this included these pages - it was more concerned with the product pages. We can likely make some basic changes but it'd be better to get some actual design input first. I will split this out into a separate issue for that purpose.
