re(frida): import-map applied to /v2 — 248 Win32 APIs named; validated

Labeled the module-resident IAT at RVA 0x16f000 (imp_<dll>_<func> x248,
0 clobbers). Validated in decomp: FUN_0044f390 -> imp_kernel32_CreateFileA
/ SetFilePointer; sleep_timer_arm -> imp_winmm_timeGetTime (pins
DAT_0056f3d4). d3d9/heap-resolved DLLs unlabeled by design.
