fix: e2e login test - handle optional Continue with Email button (twentyhq#17146)

## Summary
The e2e login test was failing because it unconditionally tried to click
'Continue with Email' button, but this button doesn't exist when
password is the only auth method.

## Root Cause
In `SignInUpWorkspaceScopeFormEffect.tsx`, when a workspace only has
password authentication (no Google/Microsoft/SSO), the effect
automatically calls `continueWithEmail()` which skips the Init step and
shows the email field directly.

## Changes
1. **loginPage.ts**: Added `clickLoginWithEmailIfVisible()` method that
only clicks the button if it exists
2. **login.setup.ts**: 
- Replaced `clickLoginWithEmail()` with `clickLoginWithEmailIfVisible()`
- Updated regex from `/Welcome to .+/` to `/Welcome, .+/` to match the
recent UI change
