Staking Portal Quick fixes

[Vesi5]

A few updates need to be made to the staking portal:

1. Hide the Farm and the Gasless staking options from the menu
2. Home page button at the bottom left corner should lead to adex.network and not ambire.com, once the website is live
3. Home & Calculator - update link, also remove Calculator if not relevant anymore
4. Help section links:
   • Terms and conditions should lead to new Terms and conditions on the AdEx website, once it is launched
   • User Guide - link to new AdEx Zendesk
   • Where to buy ADX - link to Zendesk article with exchanges

@IvoPaunov we also need to make these two additional changes:

• the subscription form in the pool section is not working. This is the list in which the emails should be kept: List token: Z8Nmu, List ID: 312400604 Tech name: 25c603c98fbbad1ef87874e96401be04
• validators stats are not showing - either remove them or add some information
• New to staking link should lead to: https://help.adex.network/hc/en-us/articles/9638410468508-How-to-stake-your-ADX-tokens-
