Migrate remaining Selenide UI tests to Playwright

[devondragon]

Summary

The project has largely moved to Playwright for E2E testing (101 tests across 14 spec files), but 9 Selenide tests remain in 2 test classes with 12 supporting page objects and utilities.

Selenide files to migrate

Test classes (9 tests):

• src/test/java/com/digitalsanctuary/spring/demo/user/ui/SpringUserFrameworkUiTest.java (5 tests)
• src/test/java/com/digitalsanctuary/spring/demo/user/ui/CompleteUserJourneyE2ETest.java (4 tests)

Page objects & utilities to remove after migration:

• 12 Page Object classes (LoginPage, RegisterPage, ForgotPasswordPage, etc.)
• 2 Utility classes (DatabaseStateValidator, EmailVerificationSimulator)
• 1 Base test class (BaseUiTest)

After migration

• Remove com.codeborne:selenide dependency from build.gradle
• Remove uiTest Gradle task if no longer needed
• Update CLAUDE.md to remove "Legacy UI tests with Selenide" line

Why

Consolidating on a single E2E framework reduces maintenance overhead, simplifies CI, and avoids contributors needing to learn two test frameworks.
