test: port tst_loginLogout

[anon-pradip]

This PR migrates the login-logout GUI tests from squish to Appium for the OpenCloud desktop client.

Changes Made:

1. pageObjects/AccountSetting.py

• Converted account_action() to use app().find_element().click() instead of squish
• Replaced squish dictionary selectors with SimpleNamespace(by=By.XPATH, selector="//Text") pattern
• Updated get_account_connection_label() to use Appium XPath finder
• Migrated wait_until_account_is_connected() from squish.waitFor() to WebDriverWait
• Added is_loading_visible() helper and wait_until_sync_folder_is_configured() with WebDriverWait
• Set ACCOUNT_LOADING locators to valid accessibility IDs

2. pageObjects/Toolbar.py

• Added QUIT_BUTTON with By.NAME, "Quit" and CONFIRM_QUIT_BUTTON with accessibility ID
• Converted quit_opencloud() to Appium: uses app().find_element().click()
• Removed squish-specific process cleanup loop

3. helpers/SetupClientHelper.py

• Added reusable close_and_kill_app() function that:
  • Quits Appium session
  • Kills remaining desktop client process via psutil
  • Resets driver for reuse
• This consolidates cleanup logic used in both mid-scenario and end-of-scenario

4. environment.py

• Refactored after_scenario() to use close_and_kill_app() instead of duplicate 8-line cleanup code

Benefits:

• Single source of truth for app cleanup
• Works for both mid-scenario (quit and restart) and end-of-scenario teardown
• Reduced code duplication

Testing:

• Tested with behave --tags=smoke features/login-logout/login-logout.feature
• All scenarios pass including login, logout, and quit client

we need to think of grouping AUT related functions in a separate file. But we can do it in the coming refactor process.

this is good enough
