fix compose config for linux

[mikeplotean]

Having issuer-service.conf and verifier-service.conf baseUrl set to service names resulted in failing to get:
http://issuer-api:7002/.well-known/openid-credential-issuer
with NS_ERROR_UNKNOWN_HOST

So it was updated to host.docker.internal.
While this worked on Windows, on Linux it threw UnresolvedAddressException.

Adding extra-hosts for wallet-api service fixes it.

Steps to reproduce:

1. run docker compose up
2. open web-wallet (http://localhost:7101)
3. issue a credential (http://localhost:7102)
4. claim the credential offer with web-wallet

Expected:

• Credential is claimed successfully
• Credential is displayed in the web-wallet credential list

Actual:

• Credential is not claimed
• Browser console logs show BadRequest (400) error
• Backend logs display UnresolvedAddressException

Acceptance criteria

Claiming works the same way on all environments:

• Windows
• Linux
• MacOS

IMPORTANT! this is a temporary solution, until a proper one is found for the failing /.well-known/openid-credential-issuer request using service names.
