Fdep::dumpSql() writes directly to cout, unlike the other dump functions (workdb_schema, workdb_rest, Call::dumpSql) which write to the ostream& parameter. This makes it impossible to redirect its output to a different stream.

Changes

• fdep.h / fdep.cpp: added ostream &of parameter to Fdep::dumpSql() and replaced all cout usage with of
• cscout.cpp: updated the call site to pass cout
• call.cpp: fixed two places where cout was used instead of of when writing NULL metric values (lines 308, 318)

Verification

Existing behavior is unchanged, the call site still passes cout, so all SQL output goes to the same destination as before. The fix just makes it possible to redirect when needed.

Closes #82 (partially)
