ci: consolidate Jira sync workflows and update to sync-jira-actions@v1

Replace three separate Jira sync workflows (new_issues.yml,
issue_comment.yml, new_prs.yml) with a single sync-jira.yml following
the recommended pattern from espressif/sync-jira-actions.

Changes:
- Migrate from espressif/github-actions/sync_issues_to_jira@master
  to espressif/sync-jira-actions@v1
- Add missing GITHUB_TOKEN permissions (contents:read, issues:write,
  pull-requests:write)
- Add workflow_dispatch trigger for manual syncing
- Add dynamic run-name for better visibility in Actions UI
