Make Client/Facture/Libellé editable in place, same as the type badge

New POST /lignes/{node}/champ endpoint (LedgerActionsController::updateField(),
whitelisted to client/facture/libelle -> field_client/field_numero_facture/
field_notes) mirrors updateType(): skips the répartition invariant check
for this save (client/facture/libellé never touch montant_ht or
field_repartition, so it can only ever leave a pre-existing historical
mismatch as it was, never introduce one), wrapped in the same
skip_validation state flag with a try/finally.

Client resolves the typed text against existing "Client" taxonomy terms
only (same known-names list the toolbar's Client filter already offers
via a datalist) -- a non-match is rejected with a clear error rather
than silently creating a new term from a typo.

Frontend mirrors the existing editingTypeId/startEditType/saveType
pattern exactly, generalized to any of the three fields via a single
{id, field} editingCell state.

Verified live: editing all three fields on a row with a known
répartition écart succeeds (bypass confirmed), an unknown client name
is rejected with a visible error and the display value stays unchanged,
and the database was confirmed clean of test artifacts afterward.
