[fix](trx-frontend-http): replay what arrived before a lazy view loaded

Opening the Map or Statistics page showed only what had been decoded since the moment it was opened, and a reload — landing straight on the tab, so its module loads at startup ahead of the history — was the only way to see the rest. Two things were being thrown away. The decode log the Statistics page counts lives in the map module, which is lazy. Recording into a module that is not loaded yet is a no-op, and unlike the map markers nothing replayed the log when it finally arrived, so every decode heard before the first visit was simply never counted. Hold those records in the client and hand them over when the module attaches. The map's own replay covered APRS, AIS and VDES, whose plugins implement syncMap, but not the grid squares: the FTx family and WSPR plotted locators as decodes arrived and had no replay at all, so everything they heard before the map loaded was lost, and the unique-grid counter with it. Both plot through a helper now, which their syncMap replays oldest first. A replayed WSPR spot carries the frequency it was heard on rather than one worked out against wherever the dial has moved to since. Pinned in decode-flow, whose history fixture gains FT8 and WSPR spots: after a first visit the statistics count every stored decode and every grid square, which before this change were 0 and 0.
