v1.4.1 — icon fix

A cosmetic follow-up to v1.4.0.

The password generator button, both Copy password buttons, the generator's Password type and the field-level Generate… shortcut wear a key icon again. v1.4.0 replaced all five with the refresh icon — a bulk glyph edit meant to correct one new button rewrote every other use of the same codepoint.

No button changed what it does, and nothing else in v1.4.0 is affected. The icons are now pinned per button by test rather than by count, since a count moves with exactly this kind of mistake.
