fix(e2e): consolidate specs into single file and fix WebDriver click issues

Tauri creates one app session per spec file; multiple files caused
invalid session id on subsequent specs. WebDriver clicks on Svelte 5
components inside scrollable panels dont trigger onclick handlers
via WebKit2GTK/tauri-driver - use browser.execute() JS clicks.
Also removed tauri-plugin-log (redundant with telemetry::init()).
