fix: code review fixes for Transaction API and Search (epic bd-8bq)

- Add safe type assertions in applyUpdatesToIssue (bd-4gs)
- Add --sort and --reverse flags to bd search (bd-4f6)
- Add test cases for SearchIssues priority range, date range, IDs (bd-ew5)
- Handle errors from GetLabelsForIssues in search.go (bd-lce)
- Standardize error wrapping to fmt.Errorf pattern (bd-7kl)
- Extract shared scanIssueRow helper function (bd-ajf)
