Fix ai-vault-panel-search test for updated consent UI

The consent dialog no longer provides a 'Not now' button; only 'Enable'
is available. Removed the test's interaction with the obsolete button
and the input clearing/refilling that followed it.

Also includes E2E failure triage report documenting nine product issues
and their associated Linear tracking.
