fix(pgxl): draw the amplifier card's meters from the amp when there is no Flex

The PowerGenius XL card gated its whole meter row on flex.amp_available, so
on any station without a FlexRadio it rendered OPERATE and the fan selector
over an otherwise empty two-column card — reported from a TS-590 station.

Nothing was missing from the backend. internal/powergenius already parses
forward power, drain current, VSWR and temperature out of the GSCP status
frame, and the docked AmpWidget already prefers the radio's meter stream and
falls back to those. Only the full card never learnt the fallback.

Same source preference as the widget, and the same two exclusions: peakfwd
and peakid are latched maxima that are never reset and survive in the
last-known status after the amp disconnects, so the plain readings are used
and gated on the transmit state instead of freezing on the last over.

The UDP path stamped the station profile, the DXCC and the QSL defaults but not SFI, A, K or distance — so an operator running digital had those fields empty across the whole log. Space weather is only stamped on a contact less than a day old: a logger re-broadcasting its backlog would otherwise be handed this morning readings for last month contacts.",
