fix: AttributeError when DRAFT_PR_TRACKING is enabled

[Copilot]

When DRAFT_PR_TRACKING is set to true, the measure_time_in_draft function throws an AttributeError: events because it attempts to call issue.events() directly on a search result object that doesn't have an events() method.

The issue occurs because:

• get_per_issue_metrics passes issue search result objects to measure_time_in_draft
• These objects have a nested structure where events are accessed via issue.issue.events()
• The function was incorrectly calling issue.events() instead of following the established pattern

Before:

events = issue.events()  # ❌ AttributeError: events

After:

events = issue.issue.events()  # ✅ Works correctly

This change aligns with the pattern used throughout the codebase in functions like get_label_events() and get_time_to_ready_for_review() which correctly use issue.issue.events().

The fix is minimal and surgical - only one line changed in the core function, with corresponding test updates to match the real-world usage pattern.

Fixes #567.

@copilot can you fix the failing github actions on this pull request?

I've fixed the failing GitHub Actions. The issues were:

1. AttributeError fix: Changed issue.events() to issue.issue.events() in time_in_draft.py to properly access events through the nested issue structure
2. Test coverage: Updated all tests to use the correct mock structure and added a specific test case that reproduces the original AttributeError scenario
3. Linting fixes: Cleaned up trailing whitespace issues

All tests now pass (115/115) and linting is clean. The GitHub Actions should now pass successfully.
