- Add `OpenAIGPTImage2` node (`node_id: OpenAIGPTImage2`) with settings
specific to gpt-image-2: quality auto/low/medium/high, background
auto/opaque (transparent not supported), all 8 popular size presets,
and custom width/height inputs (step=16, max=3840) that override the
size preset when both are non-zero
- Add `_resolve_gpt_image_2_size` helper that enforces API constraints:
max edge ≤ 3840px, multiples of 16, ratio ≤ 3:1, total pixels
655,360–8,294,400
- Add `calculate_tokens_price_image_2` using correct gpt-image-2 rates
($8/1M input, $30/1M output); price badge shows range per quality
tier with approximate flag for auto quality
- Rename `OpenAIGPTImage1` display name to "OpenAI GPT Image 1 & 1.5",
remove gpt-image-2 from its model dropdown, and update its price badge
to be model-aware with correct per-model ranges
- Add unit tests covering price formulas, size resolution logic, and
schema correctness for both nodes
