Add 0.96" SSD1306 OLED display — boot sequence, live status, 3 cycling pages

Browse Source 
Hardware: GPIO17=SDA, GPIO18=SCL, 3V3, GND — I2C address 0x3C (SW_I2C)
Library: olikraus/U8g2 (SW_I2C full-buffer mode, tolerant of missing display)

Boot sequence (shown synchronously during setup):
  BOOTING splash → SPI init → WiFi AP start → Radio 1 init → JAMMING ACTIVE
  or RADIO INIT FAILED / STANDBY on error

Live display cycles every 4 seconds between 3 pages:

Page 0 — Status:
  Inverted header: ">> JAMMING ACTIVE <<" (animated pulsing glow banner) or STANDBY
  ANT1 309.583MHz  ))) ← animated radio-wave arcs (1-3 arcs cycling ~1.1s)
  ANT2 433.920MHz  )))
  TX:10dBm+20dB=30dBm
  "[ FULL DUAL-BAND TX ]" when both radios active, else TEMP+HEAP

Page 1 — Frequency/Hops:
  R1: 309.5830MHz
      12,456 hops
  R2: 433.9200MHz
      11,234 hops

Page 2 — System Health:
  TEMP  48.2 C
  HEAP  185kB (min 183)
  UP    2h 34m 12s
  PWR   30dBm / 1000mW

Notification overlays (full-screen inverted, 2.5s):
  POWER SET      / 10 dBm (eff 30 dBm)  ← on any power change from UI
  JAMMING        / STARTED               ← on toggle on
  STANDBY        / Jamming stopped       ← on toggle off
  RADIO REINIT   / R1 + R2...            ← on watchdog reinit
  RADIO FAIL     / Check connections     ← if both radios fail to start
