[full-ci] e2e tests. fix app-provider flaky test. Disable welcome popup

[ScharfViktor]

• Disabled the welcome pop-up window for tests. I tried different methods, but found only one that works: replace usr/share/coolwsd/browser/dist/welcome to empty folder

I found another way: param --o:home_mode.enable=true disables popup but limits number of concurrent open connections to 20 that I find not problem for our tests

here is from coolwsd.xml

<home_mode>
        <enable desc="Home users can enable this setting, which in turn disables welcome screen and user feedback popups, but also limits concurrent open connections to 20 and concurrent open documents to 10. The default means that number of concurrent open connections and concurrent open documents are unlimited, but welcome screen and user feedback cannot be switched off." type="bool" default="false">false</enable>
    </home_mode>

• second popup our browser has very limited access to the clipboard, so please use the paste buttons on your on-screen keyboard instead I handle with tryCopyClipboard()

how result: tests became faster 2m52 and, hopefully, more stable

• Refactors E2E test helpers to remove ad-hoc popup handling and introduce a retry-based tryCopyClipboard function

• Removes obsolete selectors and in-test escape logic

• Consider adding a JSDoc comment to explain the purpose of tryCopyClipboard, its parameters, and retry logic for improved readability and maintenance.

const tryCopyClipboard = async (page: Page, maxRetries = 5): Promise<string> => {

.woodpecker.star:1356

• [nitpick] Ensure the relative volume path in CI config resolves correctly; adding a leading ./ might prevent path resolution issues on different runners.
