Summary

Fix notebook rendering for job stdout and stderr so angle-bracketed text is visible, ANSI colors remain styled, and output is escaped before HTML is generated.

Changes

• Escape output before converting ANSI codes to trusted color spans in both viewers.
• Add regression coverage for Python type text, ANSI styling, and script-like output.

Testing

• Ran both regression cases against the viewer classes, Python compilation, and git diff --check locally.
• The local environment lacks pytest, so the repository pytest suite will run through PR checks.

Asana task

• Not applicable; this fixes GitHub issue syft-job: job stdout and stderr HTML views drop <...> text and show no ANSI colors #9586.
