Koma task safety reports integration

[Komal362000]

Problem:
Clicking safety report links opened a standalone HTML page, losing all Sphinx navigation.

Solution:
Added a dedicated RST page per report so they appear as proper Sphinx pages with full navigation. This is a Sphinx requirement — every left sidebar entry must have its own RST file.

Why not auto-generate?
Auto-generation only makes sense when there is real logic involved (e.g. parsing 100+ C++ items). Here each file is just a title + one iframe — writing a Bazel rule for that adds more complexity than it saves.

Files changed:

File | What changed -- | -- BUILD | Added 2 new RST files to sphinx sources safety_reports.rst | Overview table with links + hidden toctree for left sidebar safety_message_passing.rst | New page showing Message Passing report via iframe safety_mw_com.rst | New page showing MW::COM report via iframe

Result: Left sidebar now shows "Safety Reports → Message Passing / MW::COM", report content only appears after clicking, Sphinx navigation never lost.
