New partners page

[Yndira-E]

Description

Added an index to the /partners page.

• We still need confirmation on whether we can use the referral partners' logos and, if so, the URLs to which they will link.
• This links to an old version of the ctlrX page, we'll need to merge this PR with the updated version.
