The forward declaration went in among the keypad-nav ones, which sit inside
#if CAP_KEYPAD_NAV. On every board without keypad navigation the declaration
vanished while the three calls stayed, so the Heltec V4 TFT and the Wio Tracker
L2 did not compile. Same trap the popup-registry declaration already documents.
Moved to where every touch board sees it. Caught by building the matrix rather
than the one board in front of me, which is the whole reason for building it.
All nine S3 envs and both ESP32-P4 targets green.
