fabi e2b7e54af9 test(e2e): fix load-induced mobile flakes (gesture timing + hydration)
Three distinct load-induced flakes in the mobile suite, all root-caused from real traces:

1. gestures-longpress "quick tap": longPress() drove page.mouse.down + Node-side
   waitForTimeout(200) + page.mouse.up — three CDP round-trips. Under load the browser saw
   the pointerup >500ms after pointerdown, firing the app's real long-press so the
   ContextSheet opened on a quick tap. New quickTap() helper dispatches pointerdown/up
   entirely in-browser on one clock, so the earlier-due pointerup always cancels the 500ms
   timer first — immune to CDP latency.

2/3. upload-cancel-confirm and sheet-escape interacted with server-rendered controls before
   Svelte hydrated them (caption fill lost -> cancel() navigates to /feed; custom role=radio
   / leave-button click no-ops). Wait for a post-hydration readiness signal (composer
   auto-focus / real profile name) before the first interaction — the same barrier the
   passing feed-based specs already have. (These are now belt-and-suspenders given ssr=false,
   but keep the specs robust regardless of render mode.)

Verified: mobile 22/22, and 0/50 full-mobile runs under load (was ~3/95 pre-fix).
