Fix memory bullet extraction in service copy

Fix services.memory bullet-list extraction by grouping the bullet/number regex before the capture, and cover both memory manager copies in the regression test.

@@ -7,12 +7,22 @@ capture group lives only in the numbered-list branch. A bullet line ("- ...")
 matches the first branch, so ``group(1)`` is ``None`` and ``.strip()`` raised
 ``AttributeError``, crashing extraction for any assistant message that contains
 a bullet list (the dominant case).

+There are two copies of ``MemoryManager``: ``src.memory`` and the
+``services.memory`` package that ``routes/memory_routes.py`` actually imports.
+The fix first landed only in ``src.memory`` while the live route path kept the
+broken copy, and this test imported ``src.memory`` so it stayed green. It now
+exercises both copies so the two cannot drift back apart.
