Demo page for signing transactions

[rsquare]

Create a dedicated page in the site template that demonstrates the process of performing a transaction signing (personal sign or eth sign) using metamask. The idea is to give a user an out of the box example of this standard and to promote the usage of signing while using nuxt-box.

[ ] Create a new page called 'signing'
[ ] Create a neat UI aesthetic for the demo ( nothing too crazy )
[ ] Create a new store called 'utils' for all the function handling
[ ] Create a button that invokes metamask to sign a simple message with a couple of data fields (maybe time?)
[ ] Display the signed hash
[ ] Recover the public key from the hash and display the address
[ ] Be creative on what a developer could find most useful on learning this concept on this page.
