Replaces qwen3-coder-480b with kimi-k2-5 across frontend configuration and UI labels, adds aliasing so the old model ID maps to the new one, and ensures LocalState persists/restores the aliased model identifier consistently.

Model configuration & aliasing frontend/src/components/ModelSelector.tsx, frontend/src/utils/utils.ts, frontend/src/state/LocalStateContext.tsx	Added public model kimi-k2-5 (displayName/shortName "Kimi K2.5", badges ["Pro","New"], requiresPro, supportsVision, tokenLimit 256000); removed qwen3-coder-480b; mapped math category to kimi-k2-5; added alias mapping qwen3-coder-480b → kimi-k2-5; LocalState now persists/restores the aliased model name.
Marketing labels frontend/src/components/Marketing.tsx	Updated AI_MODELS labels: Kimi Moonshot entry includes "Kimi K2.5" alongside "Kimi K2"; Qwen entry consolidated to single label "Qwen3-VL".

🐰 I hopped through code with gentle paws,
Old Qwen trimmed, Kimi earns applause,
Aliases stitched, state held tight,
New badges gleam in morning light—
Hop, celebrate the model swap tonight! 🎉

Greptile Summary

This PR replaces the Qwen3 Coder 480B model with Kimi K2.5 as the default Math/Coding model. The changes ensure backward compatibility by aliasing stored qwen3-coder-480b references to kimi-k2-5.

Key Changes:

• Added new kimi-k2-5 model configuration (256k context, vision-capable, Pro tier)
• Removed qwen3-coder-480b from model configurations
• Updated Math/Coding category to use kimi-k2-5 as default
• Implemented migration alias in aliasModelName() to automatically map old model ID to new one
• Applied aliasing when loading stored model selection from localStorage
• Updated marketing badges to reflect new model availability
• Removed "New" badges from kimi-k2-thinking and qwen3-vl-30b (no longer new)
