Add `custom_fields` map to IssueTemplate struct so templates can specify default values (e.g. `Priority: Medium`). On new issue form, org-level issue-scoped fields appear in the sidebar with template defaults pre-selected. NewIssuePost saves the values after issue creation. The API create issue endpoint also accepts `custom_fields` by name. Closes #493 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
