Muhammad Furqan 3747a6bfeb fix(agent/tools): PubMed tool always returns "Unknown Authors" (#16330) ...

### What problem does this PR solve?

Fixes the PubMed tool always emitting `Authors: Unknown Authors`. The
`safe_find` closure in `_format_pubmed_content` was hardcoded to search
from the article root, so the per-author `LastName`/`ForeName` lookups
never matched.

`safe_find` now accepts an optional `base` node (defaults to `child`,
preserving the existing field lookups), and the author loop passes the
current `<Author>` element.

Closes #16328

### Type of change

- [x] Bug Fix (non-breaking change which fixes an issue)
- [x] Add test cases

### Testing

Added `test/testcases/test_web_api/test_canvas_app/test_pubmed_unit.py`
covering per-author parsing, intact title/journal/DOI fields, and the
no-authors fallback.

Before: `Authors: Unknown Authors`
After:  `Authors: Furqan Khan, Jane Smith`
