fix(traces): resolve scope-context intrinsic collision in adjustTraceKey

A scope-context key that shares its name with a span intrinsic (e.g. the
scope's name addressed as {name, scope}) was resolved against the span 'name'
column when no metadata matched. Guard the intrinsic/calculated lookup in
adjustTraceKey so a scope-context key never binds to a non-scope intrinsic;
the intentionally context-blind span<->attribute remapping of legacy fields is
left untouched. This supersedes the AdjustKey change in collision.go, which is
reverted to keep the shared query builder generic.
