fix(chatmodels): add newer Azure OpenAI models

[pragnyanramtha]

Summary

• add the newer GPT-5.4 and GPT-5.5 model options to the Azure ChatOpenAI registry
• keep Azure ChatOpenAI costs aligned with the existing ChatOpenAI entries
• add a focused registry test so these newer GPT-5.x options do not drift again

Closes #6411.

Validation

• node -e "const m=require('./packages/components/models.json'); const names=['gpt-5.5','gpt-5.5-pro','gpt-5.4','gpt-5.4-pro','gpt-5.4-mini','gpt-5.4-nano']; const azure=m.chat.find(p=>p.name==='azureChatOpenAI').models; const open=m.chat.find(p=>p.name==='chatOpenAI').models; for (const n of names) { const a=azure.find(x=>x.name===n); const o=open.find(x=>x.name===n); if (JSON.stringify(a)!==JSON.stringify(o)) throw new Error(n); } console.log('azure model parity ok')"
• git diff --check
• pnpm exec prettier --check packages/components/models.json packages/components/src/modelRegistry.test.ts
• NODE_OPTIONS=--max-old-space-size=4096 pnpm --filter flowise-components test -- modelRegistry.test.ts --runInBand

Note: the first focused Jest attempt hit the default Node heap limit locally; rerunning the same focused suite with a 4096 MB heap completed successfully.

Code Review

This pull request adds several GPT-5.x models, including gpt-5.5 and gpt-5.4 variants, to the Azure ChatOpenAI provider within the models configuration. Additionally, a new test suite has been introduced to ensure that these Azure models are correctly aligned with the standard ChatOpenAI provider entries. I have no feedback to provide.
