gtkui: force GIO unix volume monitor so file choosers don't hang on dbus; Settings + panel open again; Release 1.8.1

Browse Source 
On headless/minimal desktops the gvfs org.gtk.vfs.UDisks2VolumeMonitor dbus
service often fails to activate; each Gtk.FileChooserButton then blocked ~25s on
a StartServiceByName timeout while realizing, so the Settings dialog never
appeared and the stalled main loop froze the control panel too. Set
GIO_USE_VOLUME_MONITOR=unix in run_gui() before any window is realized.

## [Unreleased]
## [1.8.1] - 2026-06-08
### Fixed
- **Settings dialog and control panel wouldn't open on some desktops.** When the
gvfs `org.gtk.vfs.UDisks2VolumeMonitor` dbus service fails to activate (common
on headless or minimal sessions), every `Gtk.FileChooserButton` blocked ~25s on
a `StartServiceByName` timeout while realizing — so the Settings dialog never
finished appearing, and the stalled GTK main loop froze the panel too. Blitztext
now selects GIO's native `/proc/mounts` volume monitor
(`GIO_USE_VOLUME_MONITOR=unix`) before any window is realized, so file choosers
open instantly with no dbus dependency.
## [1.8.0] - 2026-06-08
### Added
