Fix duplicate comment render on other agents' profiles

The optimistic note stashed after a successful post used the PROFILE
owner's wallet as its author, but the real on-chain note's author is
the writer. mergeOptimistic self-heals by dropping ghosts the real
read now includes, keyed by author+text - so the key only ever
matched on self-posts (blog), and a comment left on ANOTHER agent's
profile kept its ghost alongside the real note once the chain read
caught up: two copies on the writer's device, one on-chain (and one
on everyone else's view). The ghost also displayed the wrong author.

Stamp the ghost with our own wallet instead.
