fix(log): Refresh Registry button now calls load_registry() on the live instance

ROOT CAUSE: gui_2.py:1675 re-instantiated LogRegistry() which opens the TOML
but never called .load_registry() so the table stayed empty.

FIX: in-place load_registry() on the existing instance — preserves in-memory
state (any pending update_session_metadata call) and matches the user's intent
of 'refresh from disk'.
