- Move status page template to package-level template.Must (panic on
parse error at init instead of nil deref at runtime)
- Fix XSS in import error responses (log detail server-side, return
generic message to client)
- Handle ListenAndServe errors in HTTP and SSH servers
- Use defer resp.Body.Close() in all alert providers, check
json.Marshal errors
- Share HTTP clients across checks instead of creating per-request
- Use http.NewRequestWithContext for per-site timeout control
- Support HTTP method field (was always GET despite DB storing method)
- Implement AcceptedCodes validation (was hardcoded >= 400 despite DB
storing accepted code ranges)
- Add defer tx.Rollback() to ImportData for transaction safety
