Frank Li 2a30b01b6d MUL-5741: fix(desktop): preserve HTML attachment tab scroll position across tab switches (#6825)
Bridge the sandboxed HTML-attachment iframe's scroll position into the
per-tab scroll memento so a long report returns to where you left it after
an in-app tab switch. The preview scrolls inside
`sandbox="allow-scripts"` (no `allow-same-origin`), so the parent cannot
read its `scrollY`; an injected shim reports it via `postMessage` and a
content fingerprint invalidates a stale offset when the attachment changes.

Verified: typecheck 6/6 tasks, views Vitest 36/36, desktop Vitest 85/85,
iframe-scroll-bridge Playwright spec 6/6 on both system Chrome and bundled
Chromium.

Known follow-up: a tab switch during the attachment's loading window still
erases the saved offset (equivalent to pre-fix behavior, not a regression).

Fixes #6405
