Closes #28

Implementation details

Every manual page now shows the sphinx_rtd_theme "Edit on GitHub" link at the top, pointing to the matching .rst source in LibreSign/documentation, like the Nextcloud documentation.

Sphinx configuration

Central configuration (root conf.py)

New html_context:

html_context = {
    'display_github': True,
    'github_user': 'LibreSign',
    'github_repo': 'documentation',
    'github_version': 'main',
    'conf_py_path': '/',
}

Per-manual configuration

main/, user_manual/, admin_manual/ and developer_manual/ already do from conf import *. Each one now overrides only its own path:

html_context = {**html_context, 'conf_py_path': '/<manual>/'}

Example generated link for user_manual/start.rst: https://github.com/LibreSign/documentation/blob/main/user_manual/start.rst.

Impact

Area	Impact
All manuals	Each page shows the "Edit on GitHub" link at the top right.
Generated link	Uses blob/ (theme default), not edit/: opens the file on GitHub, one click from the edit button.
Fixed branch	The link always targets main.
Content and build	No page, route or structure changes. Configuration only.
