[feat] Add minimax API support

[anshk8]

Summary

• Added support for MinMax models (https://www.minimax.io/)

Testing

Verified locally

Local Verification:
(Note: MinMax requires $25USD minimum to test which I didn't purchase, if anyone does have credits and could help verify would be appreciated 😄 )

• I tested out setting MINMAX_API_KEY inside my .env file and startup Agenta. If no key present, I get error asking for API key. If API key is present, I get "insufficient funds" error, meaning the MinMax is being called properly!
• Also verified and got same behaviour as above for setting Standard Provider and Custom Provider in settings

Added or updated tests

Inside api/oss/tests/pytest/unit/secrets/test_utils.py I extended the existing fakeVault test so a provider_key with StandardProviderKind.MINIMAX is mapped to MINIMAX_API_KEY in the dict returned by get_user_llm_providers_secrets().

QA follow-up

• Note The Insufficient Balance and Key Not provided errors are expected, just wanted to show that it exists on all 3 enviornments

Pull request overview

Adds MiniMax as a supported LLM provider across the OSS stack (API, web UI, SDK) by wiring in the provider slug (minimax) and its API key env var (MINIMAX_API_KEY) anywhere provider kinds/secrets are enumerated.

Changes:

• Added minimax to provider/secret enums and provider label maps (web + API + SDK client types).
• Added MINIMAX_API_KEY to provider secret transform/mapping utilities and enabled-provider detection.
• Added MiniMax models to the SDK’s supported model catalog and documented the env var in docker-compose example env files.
