Fixed Staff Scheduling

Shift times are no longer crossed out

On the Staff Scheduling week, every shift's time was crossed out as if it were being cancelled. Only a shift being cancelled is now crossed out, and shift times and dates can be read in dark mode.

Every shift on the week's schedule showed its time crossed out, which is meant only for a shift someone is cancelling. That is fixed. In dark mode, the text on each shift and the day numbers above the week were dark on a dark background; they are now light, as the rest of the page is.
