feat(pin): exactly 4 digits, entered on the 4th digit

The keypad has no OK key; the 4th digit submits, so a tap that also
arrives as START can no longer submit a partial PIN (the likely cause
of "Wrong PIN" before the code opened). PINs set by earlier versions
still unlock and are then replaced by a 4-digit one. Opening an entry
ignores a second request from the same tap. A Require PIN sent from
the phone while the watch is locked now applies at the next PIN
instead of waiting for Confirm all. The linter skips .claude.
