Subject: [PATCH] fix: load binary DBCs from Data/db/ fallback path

CreatureDisplayInfo.dbc (691KB, 24K+ entries) exists at Data/db/ but
the loader only checked DBFilesClient\ (MPQ manifest) and expansion CSV.
The CSV had only 13248 entries (malformed export), so TBC+ creatures
(Mana Wyrms, Blood Elf area) had no display data and were invisible.

Now checks Data/db/ as a fallback for binary DBCs. This path contains
pre-extracted DBCs shared across expansions. Binary DBCs have complete
record data including proper IDs.
