imagery: Update i.eodag for EODAG v4 compatibility and add pyotp support

[polucifier]

Description

This PR updates the i.eodag module to ensure compatibility with the latest EODAG v4 release while maintaining full backward compatibility for users on EODAG v3. It also introduces automated two-factor authentication (TOTP) for the Creodias provider.

Solves #1659

Changes

• EODAG v4 Support: Updated internal logic to handle Pydantic-based STAC objects, new property accessors, and the transition from productType to collection.
• Backward Compatibility: Implemented a compatibility layer to detect EODAG version and switch between v3/v4 API calls dynamically.
• Automated MFA (2FA): Added integration with the pyotp library. If a totp_secret is provided in the EODAG configuration, the module now generates the 6-digit OTP code automatically, removing the need for manual terminal input.
• Improved Testsuite: Updated test_eodag.py to adapt search parameters to the installed EODAG version.
• Code Cleanup: Removed obsolete TODOs and improved inline documentation/comments.

Verification

• Verified with EODAG v4.x.
• Verified with EODAG v3.x.
• Successfully performed automated downloads from Creodias using the new PyOTP logic.
• All test_eodag.py tests passed in both environments.
