aksrt_icon_picker_assets() registers the icon-picker script as depending on
the caller's handle, so passing 'aksrt-pay-meta-box' already creates the
edge aksrt-icon-picker -> aksrt-pay-meta-box. Declaring the reverse on the
script and style closed a cycle, and WP_Dependencies' recursive resolver
never terminated, taking down every post editor and edit.php request.
Drop the reverse edge so the picker depends on the pay-meta script, not the
other way round, and contract-lock the direction.
