fix(http): /api/stats uses bb_wifi_get_rssi cache (TA-229) (#185)

the rssi lookup in stats_handler called esp_wifi_sta_get_ap_info
directly, taking the wifi driver mutex. under heavy wifi load this
blocks /api/stats for hundreds of ms — user-visible at 5s polling
cadence.

bb_wifi (breadboard v0.12.1+) already maintains a cached rssi
snapshot refreshed every 5s off the http hot path. use it.

also drop the now-unused #include "esp_wifi.h" — one less direct
esp-idf include in taipanminer code (progresses TA-235).
