- Disable BlueTooth driver by default, to ensure it doesn't allocate memory - Update BlueTooth settings app behaviour to make sure it starts/stops the devices - Disable SPI RAM usage for ST7789 as it broke App Hub - Reduce T-Display and T-Deck display buffers from 1/3rd to 1/10th of resolution - Enabled dynamic buffers for MbedTLS to optimize memory - TLS 1.3 did not work with dynamic buffers: downgrade to 1.2 for now - WiFi is now enabled from the Boot app callback to the WiFi service, instead of the WiFi service start() function. This avoids a lockup when WiFi is started by the service while the Boot app is updating the WiFi settings.
