Support deeplink/app protocol for mobile website to call transfer screen

[williamchong]

Currently we support scanning and displaying a QR code for users to tranfer LIKE, which fits desktop use case ( desktop website display QR code, users scans their desktop monitor in our app). However in mobile website it is not possible to scan QR code on a same phone.

We should support either an app protocol or deeplink in mobile. When users click such link, they should be redirected from a mobile website/app to liker land app transfer screen. The deep link should support transfer params like target wallet address/amount/memo.

We could also use deeplink on current existing https://like.co/{likerId}/{amount} website, which is currently not used anyway. When user with our app lands on the page, we could just redirect them to app's transfer screen.
