fix: source-verified corrections from review

dosbox/dosbox_pure: added validation: [sha1, size] to MT-32 ROM
entries — MUNT rejects unrecognized SHA1 (ROMInfo.cpp:171-180).
duckstation: fixed BIOS count to 105 (24 PS1 + 80 PS2 + 1 OpenBIOS).
added exclusion_note to 6 profiles with files: [] (dosbox_svn,
dosbox_svn_ce, doukutsu_rs, emux_chip8, emux_nes, fake08).
