ci(codeql): bump bundled libmicrohttpd to 1.0.3

The CodeQL workflow was still pulling libmicrohttpd-0.9.64 from S3,
which is below the project's stated minimum of 1.0.0 and is no longer
served by the bucket - the install step was failing with "gzip:
stdin: not in gzip format" because curl received a 243-byte error
response instead of the tarball. Bump to 1.0.3 from the same S3
location so CodeQL can build the project again.
