mtlcl410andClaude Opus 5.5 adc8307c0b M6: a saved Password field returns to its default value and is redrawn from it (#3926) ...

Review on #3943. A black-box test of Acrobat (synthetic form, Save As and
Ctrl+S, every decoded object searched) showed how it saves a Password
field: the typed value is nowhere in the file; a field with /DV is saved
holding /DV, one without is left empty; the asterisks are drawn from the
saved value (5 for a 5-letter default, not 13 for the typed password);
/DV and /AA are kept.

clear_password_values now does the same: it restores the (inherited)
/DV as the value, or leaves the field empty, and redraws the widgets, so
the appearance no longer shows how long the typed password was. A field
already at its default no longer counts as holding a password, so such
a form needs no cleaned copy. The parity note for form.fill-text says so
and lists the two limits Acrobat shares (a script copying the password
into an ordinary field, and an earlier revision kept by an incremental
save).

Mutants, each failing a test: no /DV restore, no redraw, the default
ignored in password_fields, emptiness ignored (an empty string in an
array). Dropping the empty-default filter was equivalent, so the filter
is gone.
