Prepare 1.0.0: fix memory leaks, use-after-free bugs, and code quality issues

- Version 6.0.0 → 1.0.0, C standard gnu17 → gnu23
- Fix desktop file path (was referencing parent directory)
- global_shortcuts.c: fix systematic GVariant/GDBusProxy leaks, guint64-to-gchar*
  type mismatch, buffer overflow risk, missing malloc NULL checks, debug artifacts
- gsr-window.c: fix notification timeout use-after-free, menu object leak in
  finalize, localtime NULL check, extract active_mode_to_string helper
- gsr-stream-page.c, gsr-record-page.c, gsr-replay-page.c: fix timer source
  leak in finalize (use-after-free if destroyed while timer running)
- gsr-shortcut-accel-dialog.c: fix Pango markup injection via shortcut titles
- gsr-info.c: fix pclose UB, replace fprintf with g_warning
- gsr-config.c: include errno in fopen failure warning
- Remove unused include, stale Phase 5 comments
