fix(telemetry): align spanmetrics dimensions, Tempo tags, and dashboard queries with C++ attribute names

Spanmetrics dimensions used xrpl.rpc.command etc. but C++ emits bare
"command". Tempo tags for phase6-added consensus/tx/peer filters used
qualified names but C++ uses bare names. Dashboard panel referenced
xrpl_tx_suppressed (never populated) instead of suppressed.
