fix(telemetry): widen only timeseries with right-side table legends

Correct the width rule from the previous layout commit. Full width
(w=24) is now applied ONLY to timeseries panels whose legend is a
right-side table, since those legends need the horizontal room. Panels
with default/bottom legends, pie charts, and the heatmap return to half
width. This narrows "Transaction Receive vs Suppressed" and "TxQ
Enqueue Rate by Transaction Type", which were wrongly widened.
