Replace the sparse Heltec V4 R8 observer home screen with a padded dark analytics dashboard, add manual display control, and make blanking a runtime setting. Dashboard (DISPLAY_ACTIVITY_DASHBOARD, the four R8 TFT observer envs): - RadioActivityWindow: 20 one-minute buckets of valid RX packets, no heap. The caller's 32-bit millis() is extended to a monotonic 64-bit clock, so nothing downstream has a rollover case; an always-on node passes 2^32 ms after ~49.7 days, which would otherwise re-enter warm-up and divide 20 minutes of traffic by seconds. Rates use 19 whole minutes plus the elapsed part of the current one rather than a fixed 1200 s. - ObserverDashboard: header, radio strip, headline totals, a 20-bar packets-per-minute graph and RF/status footers, with separate portrait and landscape layouts. A text row is a fixed 16 px, which is 3.2 logical units in portrait but 4.27 in landscape, so one shared grid would overlap. Text is trimmed by character budget, not measured width: getTextWidth() reports an over-long string at the portrait driver's fallback scale, so DisplayDriver::drawTextEllipsized() under-trims and the row renders at half height. - Six per-row signatures computed from what is actually drawn, so only the rows whose pixels changed repaint. No startFrame(), no whole-screen clear. Link state moved out of the full-frame signature, so a DHCP renewal or WiFi flap repaints one footer row instead of the panel. - Dark theme by retuning the UIColor statics at runtime, which needs no display-driver edit and carries boot, setup, reboot and power-off with it. Touch and button (DISPLAY_TOUCH_TOGGLE): - CHSC6X at I2C 0x2E, polled; TP_INT is unusable (optional R13, and GPIO 43 is U0TXD). The point-count byte is tested against a valid count, never against non-zero: an idle read returns 0xFF, which reads as a finger held down forever and latches the tap detector after one event. - turnOff() no longer parks PIN_TFT_RST low on this board. GPIO 21 is a shared LCD_RST/TP_RST net, so doing that held the touch controller in reset for as long as the display was off. Verified against Heltec's expansion-board and mainboard schematics and the V4-R8 datasheet pinout, which also correct the pin comment in HeltecV4R8Board.cpp. - The USER button click now toggles the display too; it previously did nothing whenever the display was already on. display.timeout: - `set display.timeout <secs>` / `get display.timeout`, 0 = stay on, 60 s default, 3600 max. Read live, so a change applies without a reboot and restarts the countdown rather than firing on the old deadline. - Stored in MQTTPrefs (/mqtt.json), keeping NodePrefs aligned with upstream. Runtime-only: LegacyV1MQTTPrefs and the four frozen binary payload sizes are unchanged. No JSON format-version bump - the loader skips keys no def() claims, so older firmware reads newer files and this firmware reads older ones with the default applied. Both directions are covered by tests. - Joins the observer atomic-setter contract, so a failed save rolls the live value back instead of only claiming to. New periodic work uses a wrap-safe deadline check; `millis() >= deadline` fires every loop for a whole interval before each rollover. Adds test_radio_activity_window, test_observer_dashboard (driving the real renderer against a recording DisplayDriver in both orientation profiles) and test_touch_tap_detector. 440 native cases pass.
