Active tsunami messages (NOAA/NWS Tsunami Warning Centers)

Currently-active tsunami CAP 1.2 messages retransmitted from the NOAA/NWS Tsunami Warning Centers (NTWC Palmer AK + PTWC Honolulu HI). CAP-native: severity/certainty/urgency are read verbatim from the source (severity.derivation='native'), and the full CAP block is exposed. Gated to status=Actual, non-Cancel, non-expired messages; an empty result means no active message is published. Sugra retransmits and does not issue warnings.
