fix(parsing): bail on suspicious maskBlockCount in CREATE_OBJECT blocks

When spline parsing consumes the wrong number of bytes, the subsequent
blockCount read lands on garbage data (e.g. 71 instead of ~5 for UNIT).
Previously the parser logged a warning but continued, reading garbage
mask/field data until hitting truncation. Now it returns false for
CREATE_OBJECT blocks with suspicious counts, letting the block loop
skip cleanly to the next entity.

Also downgrade ~44 diagnostic LOG_WARNING messages to LOG_DEBUG across
17 files (equipment, transport, DBC, heartbeat, chat, GO raypick, etc.)
to reduce log noise and make real warnings visible.
