analytical-viz: hot-reload guard — include model_config + model_presets, ordered

The reload guard didn't include model_config.py. When the batch (B)
field was added to TopologyConfig, Streamlit kept the stale
pre-B dataclass in sys.modules and every downstream module hit
"AttributeError: 'TopologyConfig' object has no attribute 'b'".

Fix: add model_config and model_presets to the reload list, and order
model_config FIRST so downstream modules that reload after it pick up
the new dataclass definition. Also reordered the rest so upstream
dependencies (autosuggest, memory_layout, stage_latencies) reload
before their consumers (auto_explore, auto_hardware).
