Log Message:
syncalert: live-test fixes -- UI polish, portable INI, volume persistence

A batch of fixes from SyncTERM live testing, spanning the door's own code
and small tracked patches to the vendored engine (PROVENANCE #15-20).

UI polish:
- Stats overlay (Ctrl-S) now erases to end of line before its SGR reset, so
  a shorter readout can't leave the previous longer line's tail on screen;
  the bottom row renders as a clean full-width bar (door_io.c).
- Mouse edge-scroll: widened RA's literal 1-pixel scroll border to a small
  band (scroll.cpp). Over a terminal the pointer is cell-quantized and can't
  land on the exact edge pixel -- especially the top/left, which the door
  can't snap to 0 without breaking menu-button clicks -- so edge-scroll was
  nearly unusable. No click coordinate moves, so menus are unaffected.
- Sound Controls music slider now tracks changes made from outside the
  dialog (the +/- hotkeys) without fighting the mouse: it re-syncs only when
  ScoreVolume itself changes, never overriding the gauge from its own value
  (sounddlg.cpp).

Portable per-user INI (door_io.c):
- The per-user REDALERT.INI is shared across hosts, so it must not carry
  host-specific absolute paths. UserPath is now dropped entirely (the argv[0]
  rewrite already makes the engine derive it), and DataPath is written
  relative to the per-user home via a new door_relpath() helper. Stale
  absolute keys a previous build wrote are actively removed.

Music-volume persistence and behavior:
- Root cause of "settings never persist": on exit RA re-saved the config from
  the INIClass it loaded at startup, and INIClass::Load() merges rather than
  replaces, so the reload kept the startup snapshot and clobbered whatever the
  game wrote during play. Fixed by using a fresh INIClass for the exit save
  (startup.cpp).
- Save_Settings now always writes ScoreVolume (was gated to GAME_NORMAL under
  FIXIT_VERSION_3), and the +/- hotkey persists via Save_Settings, guarded at
  the rails (options.cpp).
- Muting is respected everywhere: removed the force-to-0.4-when-muted override
  on the title screen and credits scroll (menus.cpp, egos.cpp), and stopped a
  Skirmish/MP game from overwriting the user's volume with the separate
  MultiScoreVolume -- the single music-volume setting is now authoritative
  (init.cpp).
