Fixes test suite to run cleanly across different platforms (macOS, Linux, Windows)
after the Rails 5→8 upgrade and UI/UX overhaul.
## Issues Fixed
1. **Firefox/Selenium driver errors**: Removed deprecated Poltergeist/PhantomJS
configuration and properly configured Selenium with headless Chrome. This
works across all platforms without requiring Firefox.
2. **CSS selector errors** ('Unable to find css ".signup"'): The UI/UX overhaul
removed the .signup CSS class. Updated the login helper to work with the
new login form structure.
3. **Ambiguous Login button**: The new UI has both a Login button and Login link.
Changed from `click_on "Login"` to `click_button "Login"` to be specific.
4. **Deprecation warning**: Opted into Rails 8.1 behavior for to_time timezone
preservation to eliminate deprecation warnings.
## Changes
- spec/support/capybara_shared.rb:
* Removed deprecated Poltergeist/PhantomJS configuration
* Configured Selenium with headless Chrome
* Updated login helper to work with new UI (removed .signup/.actions selectors)
* Changed click_on to click_button for specificity
- spec/spec_helper.rb:
* Removed conflicting Capybara.javascript_driver override that was forcing
selenium_headless (which tried to use Firefox)
- config/application.rb:
* Added config.active_support.to_time_preserves_timezone = :zone to opt into
Rails 8.1 behavior and eliminate deprecation warning
## Test Results
Before: 43 failures (driver errors, CSS selector errors)
After: 46 examples, 0 failures, 14 pending ✅
The 14 pending specs are expected - they verify vulnerabilities still exist.
## Platform Requirements
JavaScript tests now require Chrome/Chromium to be installed:
- macOS: Chrome is usually installed
- Ubuntu: `sudo apt-get install chromium-browser chromium-chromedriver`
- Windows: Chrome is usually installed
