docs: fix broken links found by linkcheck

- Drop the Module Index link from the root page: no Python modules are
  documented, so Sphinx never generates py-modindex.html.
- Fix the DeviceIOSession source link to the current
  src/core/deviceio_session/ path.
- Remove the reference to cmake/SetupHunter.cmake, which does not exist;
  the documented options live in CMakeLists.txt and SetupPython.cmake.
- Collapse whitespace in the code-file/code-dir role parser so
  line-wrapped 'label <path>' targets parse correctly (fixes a mangled
  replay.yaml link on the camera streaming page).
- Render the viser localhost URL as an inline literal instead of an
  auto-generated hyperlink.
