GUI: add on-screen toasts and atomic config writes

- Toast queue drawn in the top-right by the overlay, independent of the GUI
  being open. Info/warn/error colors and 6/9/12 s lifetimes; timers start on
  the first painted frame so startup messages are not missed.
- Queue a load toast after install_menu, plus warnings/errors for missing
  modules/interfaces/netvars, input hooks, fonts, ISurface, server datamap,
  and spread seed support.
- Toast on config reload, reset, bind/unbind and config save failure.
- Config saves now write `config.tmp`, flush, then rename it over the real
  file; failures leave the previous config intact.
- config_load reports whether a file was found so Reload can distinguish a
  successful reload from a missing file.
- Update CONTEXT and ISURFACE_STATUS for the single GUI, toasts and atomic
  config writes.

+- Custom immediate-mode GUI; `Insert` is the only toggle.
+- Sidebar: Movement / Combat / Visuals / Weapons / System. Cards show
+  Active + Bind and collapsible settings; System has config path, build info,
+  Reload and two-click Reset.
 - Feature gating: `feature_active(int)` (menu.cpp) — active AND
   (bind==0 or key held), used by `do_move` and the aim features.
-- Config: `$XDG_CONFIG_HOME/hl2hake/config` (fallback `~/.config/hl2hake/config`).
+- Layout (`x`, `y`, `category`, `expanded` bitmask) persists under `[gui]`.
+- Config: `$XDG_CONFIG_HOME/hl2hake/config` (fallback `~/.config/hl2hake/config`);
+  writes are atomic (`.tmp` + rename).
+- Toasts are drawn by `gui.cpp` even when the menu is closed.
