As the error message said: you are working on 2 geometries with different SRID:
the_geom column on enveloppe table has an SRID != 0.
The multipolygon you are building from text has an SRID set to 0.

Change your polygon textual representation to set an SRID equal to the
one in the_geom table, or change the_geom srid to be 0
