fix: parse_model_from_version handles both HP banner orderings

Old switches show: "HP J9298A Switch 2520G-8-PoE" (model after Switch)
Newer switches:    "HP J9565A 2520G-8-PoE Switch" (model before Switch)

New approach: strip vendor prefix + J-code + "Switch" keyword, leaving
just the product name. Returns tuple (model, part_number).
