The PR's original refactor commit only replaced the primitives (regex,
is_table_row, split_markdown_table_row) with shared imports but left the
verbatim-copied renderer (_render_table_block_for_telegram) and driver
(_wrap_markdown_tables) in place. Both are logic-identical to the shared
convert_table_to_bullets in gateway/platforms/helpers.py.
Replace both with a direct import alias. _TABLE_SEPARATOR_RE is still
imported separately because it's used by the rich-message routing logic
(lines 1024, 1044) to detect whether content contains tables.
