Crash reports carry elf_sha256 (first 16 hex chars of the crashing build's
ELF SHA-256). ELFs are now stored under that key in
{firmware_storage_path}/elf/, uploaded either with a firmware release
(optional elf_file on POST /upload and PUT /{id}) or standalone via
POST /api/firmware/elf. The ELF is validated before the release is created.
GET /api/firmware/elf/{sha} reports whether that build's ELF exists and
whether the decoder is available; POST /api/firmware/elf/{sha}/decode runs
xtensa-esp32-elf-addr2line -pfiaC over the addresses. The decoder is looked
up via settings.addr2line_path or PATH. It is NOT in the Docker image yet,
so decoding reports "not installed" until the toolchain is added; the
console falls back to a copy-paste addr2line command.
