Fix SQL INTERVAL syntax bug in metrics API

Browse Source 
Changed INTERVAL '$1 hours' to INTERVAL '1 hour' * $1 in all queries.
The previous syntax didn't properly parameterize the hours value, causing
PostgreSQL to treat $1 as a literal string instead of substituting the
actual parameter value.

This fix ensures the time range filter works correctly for all metric queries.
