Pull request overview

This PR adds end-to-end tests for paymaster support in the auth-server, building upon previous paymaster integration work. The changes convert previously disabled tests (marked with .fixme) into working tests and add new functionality to verify paymaster behavior.

Key Changes

• Modified test suite to verify paymaster button visibility and session creation with paymaster sponsorship
• Added sendTokensWithPaymaster function to enable ETH transfers with paymaster-sponsored gas fees
• Updated development server configuration to use explicit ports and environment variables for better test isolation

File	Description
packages/auth-server/project.json	Updated preview command configuration to set explicit ports (3002 for frontend, 3004 for API) and environment variables, renamed prefix from "Auth-Server:" to "Auth-Frontend:" for clarity
examples/demo-app/tests/create-account.spec.ts	Converted two .fixme tests to working tests: one verifying paymaster button presence, another testing session creation with paymaster sponsorship; simplified WebAuthn setup and improved test assertions
examples/demo-app/pages/index.vue	Added sendTokensWithPaymaster function to support sending ETH with paymaster-sponsored gas fees; changed button from "Connect (Paymaster)" to "Send 0.1 ETH (Paymaster)" shown when wallet is connected

Not sure I understand the comment about "sessions use native tx signing" and the bit about not using user ops for som TXs, everything should be not using native tx and instead use user operations AFAIK.
