feat(e2e): add waitForAllDialogsClosed method to handle dialog backdrops

[choo121600]

The should delete a connection Playwright test was consistently failing on WebKit (passes on Chromium/Firefox).

The issue was not a timeout problem. The dialog backdrop never unmounts and remains in the DOM with data-state="closed", blocking pointer events.

Root cause

Chakra v3 / Ark UI waits for animationend to unmount the backdrop, but WebKit drops this event when nested portals are present (combobox + Monaco editor in this dialog).

Fix

Add BasePage.waitForAllDialogsClosed() to ensure no dialog backdrops remain Call it after save and delete actions Remove the 30s timeout workaround
