feat(backend): credential swap to api keys in cred store

[ntindle]

Background

Many of our blocks use api keys to authenticate with various services. We want those to no longer be stored in the graph on a block level, but as a reference to a credential

Changes 🏗️

//Backend

• Swaps many blocks, but not all (LLM blocks mostly due to needing to select from many valid credentials of different providers), to the new format of credentials
• Drops discord continuous mode as a side effect, approved by Toran
• uses the store to load default set credentials for API keys injected by the system
• Uses the credit system to detect and charge for injected API keys

// Frontend

• Updates the way we handle providers in the front end to deduplicate the keys for providers we have

Testing 🔍

Note

Only for the new autogpt platform, currently in autogpt_platform/

• Create from scratch and execute an agent with at least 3 blocks
• Import an agent from file upload, and confirm it executes correctly
• Upload agent to marketplace
• Import an agent from marketplace and confirm it executes correctly
• Edit an agent from monitor, and confirm it executes correctly

🔒 Security concerns Sensitive information exposure: In several files, the API keys are being converted from SecretStr to string when used in API calls. For example, in 'autogpt_platform/backend/backend/blocks/ai_shortform_video_block.py' on line 211, api_key.get_secret_value() is used. This could potentially expose the API key if not handled carefully. It's important to ensure that these secret values are not logged or exposed in any way throughout the application.

⚡ Recommended focus areas for review Potential Security Risk The API key is now stored as a SecretStr, but it's being converted to a string when used. This could potentially expose the key if not handled carefully. Unused Import The BlockSecret and SecretField are imported but not used in the updated code. These imports should be removed. Incomplete Icon Mapping Some providers are using a fallback icon. Consider adding specific icons for these providers to improve user experience.
