Formats a number with thousands separators.

@spec format_price(number() | String.t() | nil) :: String.t() | nil

Formats a per-token model price as a per-million-tokens display.

OpenRouter pricing comes back in two shapes — newer rows use a JSON number, older rows use a stringified float. This helper accepts either and returns a rounded "$X.XX" string. Returns nil for empty/missing values so the template can render-or-skip cleanly.

Examples

iex> EndpointForm.format_price(0.0000015)
"$1.50"

iex> EndpointForm.format_price("0.0000015")
"$1.50"

iex> EndpointForm.format_price(nil)
nil

Returns parameters supported by the model, filtered to ones we have UI for. Groups them by :basic and :advanced.

Renders a single model option as a clickable card with name, ID, context-length / max-output badges, and prompt / completion pricing.

The same card is used in two places:

• Inside the model grid — the operator's browse surface. Click selects. The currently-selected card is excluded from the grid (it's hoisted to the top — see below) so each model appears in exactly one location.
• Hoisted above the grid as the "Current Model" — when @selected_model is set, the card moves out of the grid to the top of the section. show_clear: true adds an "X" button that deselects (drops the card back into the grid). Clicking the card body itself is a no-op (selecting an already-selected model has no effect).

This keeps a single source of truth for the rich model display — badges + pricing — instead of duplicating the layout between a separate summary panel and the grid.
