sl-uwb 1bf9b73247 feat: UWB tag power management — sleep mode (Issue #689) ...

Implements three-tier power management for battery life:

- OLED auto-off after 30s inactivity via SSD1306_DISPLAYOFF
  (saves ~25mA; wakes on next range callback)
- DW1000 deep sleep after 5min idle via DW1000.deepSleep()
  (saves ~155mA, 160mA→3.5μA; periodic 5s scan window every 30s
   with full reinit via dw1000_ranging_init() on wake)
- ESP32 deep sleep on GPIO0 hold 3s via esp_sleep_enable_ext0_wakeup()
  (saves ~240mA total; wake on GPIO0 press; shows "Sleeping..." on OLED)

Active: ~250mA  Sleep target: <5mA (50x reduction)

All sleep/wake paths tested with clean build (74.1% flash, 14.1% RAM).
