Display: switch pushPixelsDMA to blocking pushPixels to prevent SPI bus contention between the display and SX1262 radio on the shared FSPI bus. LXMF: add opportunistic-first delivery with background link upgrade. First message to a peer sends immediately via opportunistic packet. A link is established in the background; subsequent messages use the link when active (prepending dest_hash for Python DIRECT format), falling back to opportunistic otherwise. No user-facing delay.
