Improved permissions for conditional questions

[hlbmtc]

Summary by CodeRabbit

• Bug Fixes
  • Conditional questions now verify that referenced condition and child questions are viewable before creation or update.
  • Private, hidden, missing, or unattached source questions are rejected consistently, preventing inaccessible questions from being used in conditional content.
  • Viewable questions and the creator’s own permitted private questions continue to work as expected.
  • Hidden and nonexistent questions return indistinguishable validation results.

📝 Walkthrough

Walkthrough

The serializer validates condition and child question IDs through a permission-filtered queryset. Non-viewable questions return a generic existence error. New tests cover creation and update permission behavior.

Changes

Conditional question visibility

Layer / File(s)	Summary
Viewable question validation questions/serializers/common.py, tests/unit/test_questions/test_conditional_permissions.py	ConditionalWriteSerializer shares a permission-filtered question lookup for condition and child validation. Non-viewable or missing questions return the generic error. The tests cover private, hidden, missing, unattached, viewable, creator-owned, and update cases. Import ordering changes have no functional effect.

_{A rabbit checks each question’s sight,
Hidden paths now fail outright.
Conditions share one guarded gate,
Child links meet the same fate.
Tests hop through private and clear,
And valid sources pass with cheer.}

Inline comments:
In `@questions/serializers/common.py`:
- Line 286: Remove the unused required label parameter from
_get_viewable_question and update validate_condition_id and
validate_condition_child_id to call it with only the question ID, preserving
conditional create and update validation.

In `@tests/unit/test_questions/test_conditional_permissions.py`:
- Line 85: Update the affected assertions in the conditional-permissions tests
to expect the serializer’s generic “Question ID does not exist” validation
message instead of “Condition does not exist,” covering the cases referenced
around the existing assertions while preserving the surrounding test behavior.
