touch: beta_47 — Discover app (find/list/map nearby nodes + wardriving), Attaky release wiring, P4 LCD

Browse Source 
- New Discover app: active NODE_DISCOVER sweep -> signal-ranked nearby list, tap-to-add-contact, GPS wardriving log (SD CSV) + signal-coloured coverage overlay on the map. Board-agnostic.
- T-Display P4 TFT-LCD (HI8561) variant support (WADA_P4_LCD build; AMOLED bin untouched).
- Wire the Attaky Core board (#158, @attakygit) into the release matrix + web flasher.
