[fix](trx-frontend-http): make map links work before the map has loaded

The AIS and APRS mini views link each position to the map, and neither
did anything: the map module installs itself lazily, and it was the one
defining window.navigateToAprsMap, so until something had opened the Map
tab the global did not exist.  AIS calls it inline from onclick and
threw "not a function"; APRS guards the call and so failed silently.
The grid links on FT8, FT4, FT2 and WSPR rows went the same way through
navigateToMapLocator.

The app owns both globals now, installed at startup.  They record the
target, switch tabs through navigateToTab — the only path that
materialises the panel from its template, loads the module and updates
the history entry, none of which the module's own hand-rolled tab switch
did — and the target is applied once the module reports ready.

The module keeps the focusing, which is its job, and exposes it as
focusMapPosition and focusMapLocator.

The smoke test now calls the link from a cold page, asserting the map
module is not loaded first so the check cannot pass by accident.
