fix(esp): reduce RAM pressure and TDeck display stalls

Tune Arduino task stacks and board env flags to recover internal RAM for BLE startup.

Avoid synchronous boot UI rendering on Arduino loopTask and move large board singletons toward PSRAM where available.

Improve TDeck/Pager display responsiveness by restoring practical LVGL DMA buffers, using SPI pixel writes, disabling transition animations, and testing TDeck display SPI at 80MHz.
