Add `openstatus status-report` (alias `sr`) command group with 6 subcommands: - list: list reports with optional status filter and pagination - info: show report details with update timeline - create: create a report linked to a status page - update: update report metadata (title, components) - delete: delete a report with confirmation prompt - add-update: add timeline entry with status transition Extract shared auth interceptor and base URLs into `internal/api/` so both monitors and status-report packages can reuse them.
