ARCH §8.6 specifies a dual-event contract on logic changes — a
`field.updated` row carrying old/new diffs of the reconstructed JSON
shape, plus a semantic `field.conditional_logic_replaced` row from
inside `replaceLogic()`. The semantic event is already pinned by
`FormFieldConditionalLogicServiceTest`. The diff payload contract was
documented but unasserted.
Two new tests:
- `test_field_updated_activity_log_contains_conditional_logic_diff_when_tree_changes`
Pins old/new payload shapes via byte-equal `json_encode` comparison
(mirrors ConditionalLogicSnapshotAndResourceParityTest's
associative-array key-order trap). Both rows share the same
causer_id.
- `test_field_updated_without_logic_change_does_not_emit_conditional_logic_diff`
Pins the negative: bare label-only updates must NOT carry a
`conditional_logic` key in the field.updated payload, and must NOT
emit a semantic `field.conditional_logic_replaced` row.
The first test passed against the original implementation; the second
required `FormFieldService::update()` to filter `conditional_logic`
out of the activity-log payload when the reconstructed shape didn't
change between pre- and post-write. Adjustment lands in this commit:
the `$before` / `$new` arrays now only carry the key when
`$currentConditionalShape !== $newConditionalShape`.
Tests: 1148 → 1150 green (3099 → 3110 assertions).
