feat(ui): add MongoDB Atlas provider support

[danibarranqueroo]

Context

This PR brings full MongoDB Atlas coverage to the Prowler UI. Until now Atlas was only available via the CLI/API; UI users couldn’t add or manage Atlas organizations or upload API keys. With these changes, the web onboarding flow and provider management screens now treat MongoDB Atlas as a first-class provider, enabling credentials management through the browser.

Description

Complete MongoDB Atlas UI integration:

• Adds MongoDB Atlas as an option throughout the provider workflow: radio selector, enhanced lists, filters, overview cards, and badges (including a dedicated Atlas SVG logo centered within the standard 256×256 badge frame).
• Implements the Atlas credential form with Public Key / Private Key fields, validation, and FormData wiring so secrets are encoded correctly and sent to the backend via the existing provider secret pipeline.
• Updates provider schemas, types, and default values so Atlas UIDs/aliases validate alongside AWS/Azure/etc., and the onboarding step prompts for the Atlas Organization ID with the correct hinting.
• Extends the providers list/filtering/enhanced selectors so MongoDB Atlas accounts can be filtered and displayed consistently (accounts selector, overview cards, filters, etc.).
• Hooks Atlas into the global provider help text so “Read the docs” points to the MongoDB Atlas onboarding guide.

Authentication method:

• MongoDB Atlas API Key (public key + private key scoped to an organization ID)

This gives UI parity with the API: you can now connect MongoDB Atlas organizations, upload API keys, and see Atlas providers everywhere in the interface.
