Honor repository selection for PR and issue status bars (#8416)

* Initial plan

* feat: honor repository selection for PR and issue status bars

Listen to repository.ui.onDidChange event to track when the user
switches between repositories. The PR status bar item and issue
status bar item now show only when their respective repository
is selected in the VS Code UI.

* refactor: address code review feedback

- Use definite assignment assertion for _isRepositorySelected field
- Update updateStatusBarVisibility to also handle switching state

* refactor: extract showStatusBarIfSelected method

Extract the repeated pattern of checking _isRepositorySelected before
showing the status bar into a dedicated private method.
