Optimizations to convert users

[has-n]

1. made main nav bar logically consistent albeit longer (eg - Cloud doesn't belong under Product but Code Navigation should)

2. added CTA where value proposition is presented - user should be able to visualize how that VP will help them specifically

3. identified another use case for the Code Security usecase

4. view sample searches customized to user's preferred language (it's supposed to be a dropdown but I haven't used Tailwind before)

5. track user intent through flag for [2] above, if the user clicks through the CTA, a flag identifying their area of interest is appended to the URL. This can feed into the ABM tool to track who cares about what.
