Description

Remove the Sphinx warnings that appeared on the API pages of dicogis.ui now that PyQt6 is installed in the documentation build (#532):

• six module docstrings raised "Unexpected indentation": the Name/Purpose/Author headers of wdg_tab_publish, workers, progress and read_vector_flat_dataset become a reStructuredText field list, and the continuation lines of ui/main and mw_dicogis are dedented;
• the unescaped *.dbconf of read_db_conf is put in a literal;
• PyQt gives every signal without a docstring of its own a generic one containing *types, read as an unfinished emphasis: a small autodoc-process-docstring hook in docs/conf.py drops it and leaves the signals documented by hand untouched.

The six docstrings were checked with docutils and the hook on a minimal Sphinx project; the full build has not been run locally (it needs GDAL), so the CI run of this PR is the confirmation.

Follows #532.
