🤖 feat: Support o4-mini and o3 Models (#6928)

* feat: Add support for new OpenAI models (o4-mini, o3) and update related logic

* 🔧 fix: Rename 'resubmitFiles' to 'isResubmission' for consistency across types and hooks

* 🔧 fix: Replace hardcoded 'pending_req' with CacheKeys.PENDING_REQ for consistency in cache handling

* 🔧 fix: Update cache handling to use Time.ONE_MINUTE instead of hardcoded TTL and streamline imports

* 🔧 fix: Enhance message handling logic to correctly identify parent messages and streamline imports in useSSE
