fix(images): normalize shell scripts to LF line endings

database image crashed at start: CRLF shebang in start.sh made the kernel
look for interpreter '/bin/bash\r'. Other image Dockerfiles mask this with
dos2unix at build time, but scripts/images/database/Dockerfile does not.
Convert all tracked .sh files to LF and pin eol=lf via .gitattributes.
