Privado documentation and integration for KYC

**USER STORY**
As a Team Member or KOL I want to donate early, so that I can get tokens I believe in at a better price and get access to an exclusive community

**ACCEPTANCE CRITERIA**
Given that I am a Team Member or a KOL with an invite-only NFT, I have signed-in and I enter an Early Access Round

1. I am first required to pass KYC (redirected to Privado ID - https://www.privado.id/)

2. I can then see details about the round:
• Expected price
• Details on the lock-up terms (content TBD)
• A short description on what to expect (content TBD)
• Donate CTA

2a. I am shown the maximum I am allowed to acquire (=2% of total supply) and the corresponding cost in MATIC/POL.

3. I can donate POL (on completion of step 1) and sign-up for email or TG updates

4. I am shown a confirmation (content TBD) and link to the Claims Dashboard (Token view page) where I can claim my tokens over the vesting period.
