Values come from ESPHome's own hint in the log of each online device
("Set flash_chip: ... to save IRAM"). Devices that were off got the value of
an identical board (ESP32-PICO-D4 ATOM/Stamp Pico: gd, JC3248W535: generic,
POW Elite: gd), marked as not read from the device.
Extract shared M5ATOM vehicle code (esp32, on_loop, LED effects) into
common/vehicle_base.yaml, reducing each vehicle file from ~136 to 20
lines. Remove dead commented-out code from on_loop lambda.
Gate: fix on_multi_click and select indentation, change
esp32_ble_tracker id from ${name} to ${device} (lowercase),
remove unused commented-out gate_flash GPIO sensor.
