Sort issues by ID when showing multiple issues

When bd show displays multiple issues, they are now sorted by ID
for consistent and predictable ordering:
- bd show bd-7 bd-5 bd-6 displays them as bd-5, bd-6, bd-7
- Works with explicit IDs, --all-issues, and --priority flags
- Applies to both text and JSON output
- Uses alphabetical sorting which works for typical ID formats

This makes the output easier to read and more predictable,
especially when showing many issues at once.
