Fix letter-named patch MPQs not loading on case-sensitive filesystems

Two bugs in loadPatchArchives():
1. isLetterPatch detection was inverted (rfind != 0 is false for all
   "patch-*" entries), making the disable flags non-functional
2. Patch file lookup used exact std::filesystem::exists() which is
   case-sensitive on Linux — Patch-A.MPQ wouldn't match patch-a.mpq

Now scans the data directory once and builds a case-insensitive lookup
map, so any case variant (Patch-A.MPQ, patch-a.mpq, PATCH-A.MPQ) is
found correctly.
