feat(scan): binary FIX scan reads frl_/frd_ names from .aep (no AE, never hangs)

Root cause of 'stuck on AE': heavy expression-driven projects take >10min for AE
to open, exceeding the scan timeout → job dies → admin UI stuck 'scanning'.

Fix: extend the stdlib .aep RIFX parser to collect every Utf8 name (ParseNames),
since FIX media placeholders are renamed footage ITEMS (frl_c1m1), not layers, and
text are layer names (frl_c1t1) — both are Utf8 chunks. QuickScan now branches on
?mode= (or auto-detects frl_ names) and scaffolds FIX scenes/elements + frd_*color
slots directly from the binary. Verified on the real final.aep that timed out in AE:
1 scene, 6 elements, 4 colors in 0.5s vs 10-min AE timeout.

Admin 'Quick scan (no AE)' is now the recommended path and passes the project mode.
