Display metadata for a trace-specific rotor "filter" unit — a navigation
mode that walks only the points matching some predicate (e.g. only bullish
candlesticks). Unlike the two built-in compare units (lower/higher value),
a trace can expose any number of filter units.
key: stable identifier the trace uses to recognise the unit when the
rotor asks it to move (see AbstractTrace.moveToRotorFilter).
label: the rotor unit name announced when cycling with Alt+Shift+Up/Down.
noun: the phrase used in "No {noun} found ..." boundary messages.
