Refactor the coder's new memo-reply and reply-thread-page tests to use
the shared test helpers (fake wallet, MemoAction tests, page-controller
tests, page submit tests, page build wiring). Extend the memo-action and
page-build helpers to support the reply slice's extra parent-txid
argument and byte-based multi-byte tests. Behavior is preserved; all
unit, property, and acceptance tests pass.

Extract shared test helpers for the Memo post and Set Name behavior
slices: fake wallet/profiles, MemoAction tests, page-controller tests,
page build wiring, and shared property-test invariants. Behavior is
preserved; all unit, property, and acceptance tests pass.
