fix: expand Runware pricing whitelist to all 15 registry models (v0.14.0)

All Runware model selections except schnell and dev were silently falling
back to runware:100@1 (FLUX.1 schnell) because COST_PER_IMAGE only had 2
entries while the image model registry (v0.13.8) expanded to 15 models.

resolve_model() falls back to schnell for any ID not in COST_PER_IMAGE,
so SD3, FLUX.2, HiDream, TwinFlow, Z-Image, Qwen-Image, Krea, and
GLM-Image all generated schnell images regardless of admin selection.

Fix: add all 15 Runware model IDs to COST_PER_IMAGE and DEFAULT_STEPS
with costs from runware.ai/pricing (April 2026). Add @see cross-ref to
the registry to prevent future drift when new models are added.

+## [0.14.0] - 2026-04-26
+
+### Fixed
+- Runware image generation now correctly uses the admin-selected model instead
+  of silently falling back to FLUX.1 schnell (runware:100@1) for all non-schnell
+  and non-dev selections. Root cause: `class-runware-image-pricing.php` only
+  had 2 models in its `COST_PER_IMAGE` whitelist (schnell + dev), but the
+  image model registry was expanded to 15 Runware models in v0.13.8 without a
+  matching update to the pricing class. Any model ID not in the whitelist caused
+  `resolve_model()` to fall back to schnell, so every Stable Diffusion, FLUX.2,
+  HiDream, TwinFlow, Z-Image, Qwen-Image, Krea, and GLM-Image selection was
+  silently downgraded.
+- Added all 15 Runware model IDs to `COST_PER_IMAGE` and `DEFAULT_STEPS` with
+  correct per-image costs and step counts sourced from runware.ai/pricing (April 2026).
+- Added `@see` cross-reference to `class-image-model-registry.php` in pricing
+  class docblock to prevent future drift.
