Live-expose workspace.per_monitor, titlebar buttons, and desktop icons

Closes the remaining "config-file only" gaps from the AGS capability
survey. workspace.per_monitor gets srd set per_monitor <bool> - safe to
flip live since a monitor with no per-monitor override already falls
back to current_workspace regardless of mode, so nothing visually jumps
on toggle.

theme.decorations.title_bar.button_style/button_side/button_order and
general.desktop_icons/desktop_icons_all_monitors all get the same
live-set + SettingsResponse readback treatment as everything else this
session. New srdwm_core::format_button_order is parse_button_order's
exact inverse, so button_order's readback matches the same string shape
srd set itself accepts.
