The send path always base64-encodes (seal_b64), but the receive path only
called open_b64 when crypto was enabled — so with an empty account (crypto
disabled) the base64 layer was never undone and clipboards arrived as
"aGVsbG8tb3Zlci1sYW4=" instead of "hello-over-lan".
Make open_b64 unconditional, symmetric with the always-on seal_b64: it
base64-decodes then open()s, which passes through when crypto is disabled.
The file path already uses raw seal/open with no base64, so only the text
path needed the change. Pre-existing since the E2E commit 33d0fb7.
