Drop the top-right "cached" label from the assessment card — it surfaced
an implementation detail and read as if the insight were second-hand. The
warm cache still backs the text; the card just no longer announces it.
Mount the "show more" toggle only when the clamped prose actually
overflows three lines, measured against the live layout via a
ResizeObserver instead of a character-count guess. Short assessments that
fit no longer grow a toggle that reveals nothing, and text that wraps past
three lines on a narrow column now gets one.
Move the toggle copy off the inline locale-prefix fallback onto proper
`insights.assessmentShowMore` / `insights.assessmentShowLess` keys across
all six locales, and right-align the "last updated" line.
