isra el 83d0c3803a fix(web): stop the SupportHQ widget rebuilding itself on every session refetch
The effect depended on the whole session object. SessionProvider returns a
new object on every refetch, and React compares deps by reference, so an
identical session still ran the cleanup and the body again: the widget was
destroyed and its script re-injected even though nothing about the user
had changed, closing any chat the user had open.

It now depends on the individual strings the effect actually reads, which
compare by value, so it only re-initialises when the metadata genuinely
changes.

Two related leaks fixed at the same time:

- cleanup called destroy() but left the script tag in the document, so
  every re-run added another one for the life of the page. It is now
  removed.
- a script whose src is already cached can finish loading after cleanup
  ran, and initialising then left a widget behind that nothing would
  destroy. That late load is now ignored.

Tests cover all four behaviours and fail against the previous version.

Also gives the API guide page focus before the clipboard test: writeText
rejects on an unfocused document, which is where a page sits while other
workers run, and granting clipboard permissions does not cover it.
