The access-rules form is large for every file rule, so the block now
collapses to its header (a toggle carrying the rule count) and hides
entirely when None is selected - the header keeps the title and the
None/Check radios, so re-enabling is one click (Check also reopens the
block). The expanded state is transient editor UI state (a module map
keyed by the rule index), kept across the editor's re-renders; a rule
without accessRules starts hidden and Check creates the empty block to
build rules in.
Tests: collapsed by default (header + count, no rows), expanded rows,
None and no-accessRules hidden, the enabled-but-empty hint, and the
radio driving the visibility. 882 frontend + 858 Python; sw cache
simple-v424.
