Fix modal z-index stacking issue caused by sidebar layout

Browse Source 
Move decorative gradient glows from ::before/::after pseudo-elements on
.app-main to a separate .app-glow div. The pseudo-elements were creating
a stacking context that trapped Bootstrap modals (z-index 1055) inside
.app-main, while the backdrop (z-index 1050) was appended to <body> —
causing the backdrop to render on top of the modal content.
