feat: expose model prices on GET /v1/models - #6

Conversation
Clients that show spend (OpenCode and the like) had no way to read what the proxy bills a model at without an admin key. `include_pricing=1` adds `pricing` (per million units) and `pricing_inherited` to every entry, resolved the way the data plane resolves them, so a client's arithmetic matches the proxy's accounting. Off by default, so the public list keeps its OpenAI shape. The parameter needs an API key or session, like `include_hidden`: prices are operator data, and anonymous callers see none. Price lookup moves out of modelView into modelPricing, shared by the admin view and the list so the two cannot drift.

What
GET /v1/models?include_pricing=1adds two fields to every entry:{ "id": "qwen-72b", "object": "model", "owned_by": "vllm-1", "pricing": {"input_tokens": 0.4, "output_tokens": 1.2}, "pricing_inherited": false }Why
A client that prices its own requests (OpenCode, for one) otherwise carries its own cost table, or asks an admin endpoint it has no key for. The prices are per million units and resolved in the same order the data plane resolves them (own name, the model it points at, upstream name), so what the client multiplies by is what the proxy bills.
