fix(campaigns/parse): keep no-name rows + surface skip breakdown

Map CSV rows that had a valid email but no name in the source column
were silently dropped at parsing — that's why a campaign would end up
with N unpaired Giftbit shortlinks for N "missing" contacts that
weren't actually missing, just nameless.

The send worker already handles a missing firstname by substituting
"cher client" / "dear customer", so dropping the row was wasteful.
Now we keep the contact and surface a name_warning on the row so the
operator can either edit the firstname in Step 2 or accept the
default.

Also added counters for previously-silent skip paths:
- duplicate: row's email was already seen above (1 gift / household
  consolidation, depending on the multi setting)
- multi_skip: couple skipped because multi='skip' was selected

Wizard Step 2 imbalance banner now ventilates the skip breakdown so
the operator understands exactly where the N "missing" contacts went:

  Ventilation des contacts droppés au parsing du Map CSV (sur 213
  lignes brutes) : 8 sans email valide · 5 emails en double · 0
  couples ignorés · 3 sans nom (gardés, utilisent "cher client" à
  l'envoi)

Unrelated reassurance on the question that triggered this: language
fallback to French is already in place (matchCustomer returns
language:'fr' on miss, worker reads (r.language || 'fr')) so any
unmatched recipient gets the FR template, never an English one by
default.
