Dynamic routes

[TrustfulDev]

Adds dynamic page routing to the details page. The searchbar state is now passed properly into the Details page and Payment page.

• Tweaked Payment.css
• Removed all (except the description) filler data and replaced it with the state data
• Adds a cancel button to the payment page to navigate backward
• Removed some unused code

NOTE: The code breaks if input fields are left empty in the searchbar.
