ergosteur d2ff9d2617 Fix stored-HTML-injection: escape AD data before it hits Markdown tables
Every table cell fed from directory content (descriptions, sAMAccountName,
OS strings, DNs, object classes) was interpolated into the Markdown report
raw. python-markdown doesn't escape inline HTML by default, so a
directory-controlled value like an OU description containing <script>...
would render live once the report was converted to HTML with md_to_html.py
-- and the underlying data is attacker-influenceable, not just
operator-authored.

Added md_escape() (Python) / ConvertTo-MdSafe (PowerShell), applied at
every table-row interpolation in both scripts. Escapes &, <, > to HTML
entities and | plus embedded newlines to keep the table structure intact.
Raw JSON dumps are left untouched -- this only affects the Markdown/HTML
presentation layer.

Verified end-to-end with <script>, <img onerror=...>, embedded &, and
embedded | payloads across every affected table in both scripts; confirmed
no live tags reach the rendered HTML and no double-escaping occurs.
