PostgreSQL + Ivanti API enrichment can return non-string values
(objects/arrays) for currentStateUserNotes and similar fields.
React crashes silently (blank page, no console error) when trying
to render non-string values as children. Same root cause pattern
as Bug 3 in ivanti-panel-bugs-2026-05-12.
Added safeText() wrapper that coerces any non-string truthy value
to a JSON string before rendering in the History tab notes section.
Also fixed flaky property test: fc.date() could generate invalid
dates causing RangeError on .toISOString(). Added .filter() guard
and explicit UTC date bounds.
