Description of Changes

Added ability to buy tokens from the explore page.

"How We Fixed It"

N/A

Test Plan

1. Create a new token
2. Visit the explore page and attempt to buy that token (ignore the pricing data - its placeholder)
3. In the buy modal verify you correctly see the eth amount in your selected address
4. Verify the dollar amount you enter correctly translates into eth amount
5. Verify you are able to see receipt details correctly (tokens bought are hardcoded for now)
6. Verify you are able to buy the token successfully
7. Verify the modal closes after the token is bought successfully
8. Verify you get joined to the token community if not already joined after a successful token purchase.

I got some weird errors (from libs/model/src/community/UpdateCommunity.command.ts) when updating the community namespace after creating a token. ATM I just commented out the code that was causing errors.

Also, libs/schemas/src/entities/token.schemas.ts was throwing weird zod type errors and failing create token call, cause of the initial_supply field, atm I added .any() to bypass that.

@kurtisassad - would appreciate your help on these 2 things.
