Retry EPUB section build after freeing BLE stack

Browse Source 
When building an EPUB section fails with Bluetooth enabled, temporarily stop the BLE stack to free up memory (~16KB), retry the build, then restart BLE. This works around memory fragmentation caused by the NimBLE stack that prevents allocating the large contiguous buffer needed for inflate/deflate operations. The recovery only runs once per uncached chapter since chapters are cached afterwards.
