Release 1.4.1: a Bonded checkbox in the terminal tables

The config's per-terminal bonded key becomes editable in the dialog
(previously file-only, shown as a text suffix): checked, the
terminal's contacts short into one internally joined lug - the total
value stays prescribed, the per-contact split is a solve outcome.
Same-name rectangle groups seed it checked as before; unchecking one
falls back to the per-cell area share, and checking a single-contact
terminal gives it an equipotential-lug contact instead of uniform
injection. Save config... writes the flag back (removed when
unchecked - false is the schema default). With this, every
non-structural terminal option (active, values, v_oc, contact layer,
bonded, comment) is table-editable.
