Silo v3 onboarding

[silochad]

Run yarn dev in projects/ui so that you get the netlify endpoint

Forking at block 17251906 which is right after EBIP-8 deployment

Manually fetched the deposits at this block for the BFM (0x21de18b6a8f78ede6d16c50a167f6b222dc08df7) and overrode those in deposits.json:

{
  "data": {
    "farmer": {
      "id": "0x21de18b6a8f78ede6d16c50a167f6b222dc08df7",
      "deposits": [
        {
          "token": "0x1bea0050e63e05fbb5d8ba2f10cf5800b6224449",
          "season": 6612,
          "amount": "532690",
          "bdv": "118361"
        },
        {
          "token": "0xbea0000029ad1c77d3d5d23ba2d8893db9d1efab",
          "season": 11883,
          "amount": "377060000000",
          "bdv": "377060000000"
        }
      ]
    }
  }

• Add onboarding flow
• Add migration button
• Replay onboarding after migration
• Load deposits from static JSON if user hasn't migrated, otherwise use sdk.silo.getBalances()
