Backport from Friends of Joanna: renamed the bool member `unk5d5_06` in
the `menudata` struct to `isdialogopen` to clarify its purpose as a
dialog state flag. Also renamed the local bool variable `sp344` in
`menutick.c` to `isdialogopen` to reflect its relation to the struct
member. Updated all references for consistency and improved readability.
