Jacob Dahl 26969c25ff fix(uavcan): close directory before processing files in migrateFWFromRoot (#26676)
migrateFWFromRoot held the SD root directory open via opendir/readdir
while performing heavy file I/O (getFileInfo, copyFw, unlink) inside the
loop. Between readdir calls the FAT semaphore is released, allowing
other tasks (e.g. logger) to dirty the shared FAT sector cache. When
the next FAT operation needed a different sector, fat_fscacheflush
would write the dirty data followed by an immediate read — triggering
a write-busy to read transition in the SDMMC WRCOMPLETE path that
kills the SD card on STM32H7.

Split into two phases: first collect .bin filenames with the directory
open, then close it before doing any file I/O. This also fixes a
missing closedir on the mkdir error path and avoids modifying directory
entries (via unlink) while iterating them with readdir.
