fix(M05): ensure config exists so opts.data populated for test_opts_override

When opts.load() gets FileNotFoundError, opts.data = {}.
temporary_opts only applies overrides for keys in opts.data.
Initialize fixture now creates minimal config.json when missing.

+
+### Failure
+
+When `opts.load()` gets `FileNotFoundError` (no config.json), it sets `opts.data = {}`.  
+`temporary_opts` only applies overrides for keys in `opts.data`, so no overrides are applied and `samples_save` stays at its default (True).
+
+### Fix
+
+Ensure a minimal config exists before loading webui so `opts.data` is populated.  
+Updated `test/conftest.py` `initialize` fixture to create `config.json` with `{"samples_save": True}` when missing.
