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. By refactorer.

Unit tests for the Memo set-name behavior slice (src/services/memo-set-name.js).
|
|
|
|
These tests express the observable behavior described by specs/set-name.feature:
|
|
- a valid name broadcasts an OP_RETURN transaction carrying the Memo set-name
|
|
prefix (0x6d01) and the name text, and the profile store reflects the new
|
|
name.
|
|
- an empty name is rejected with a validation error and nothing is broadcast.
|
|
- an over-long name is rejected with a length error and nothing is broadcast.
