elf-san wa yaserarenai character names tidy up/regularization

BUR #31517 has been rejected.

rename satero -> satero_(elf-san_wa_yaserarenai)
rename honeda-san -> honeda-san_(elf-san_wa_yaserarenai)
rename ino_akiho -> ino_akiho_(elf-san_wa_yaserarenai)
rename kusahanada -> kusahanada_(elf-san_wa_yaserarenai)
rename medesa -> medesa_(elf-san_wa_yaserarenai)
rename naoe_tomoatsu -> naoe_tomoatsu_(elf-san_wa_yaserarenai)

So that all the names from the elf-san_wa_yaserarenai. manga/anime by synecdoche follow the same trend, keeping things neat and tidy

I see no need to qualify an unambiguous full name tag like Naoe Tomoatsu just because the other characters in the copyright have qualified tags.

None of these are ambiguous.
