feat: add remove_mfa_by_public_address to User resource

[bo-magic]

Summary

Adds User.remove_mfa_by_public_address(public_address) to the Magic Python Admin SDK, letting developers remove (deactivate) all MFA for one of their app's users, identified by the user's public address. Useful for support flows where a user is locked out of their authenticator.

• New User.remove_mfa_by_public_address(public_address) method + v1_user_remove_mfa = "/v1/admin/user/remove_mfa" endpoint constant — mirrors the existing logout_by_* plumbing, deriving the issuer via the existing construct_issuer_with_public_address helper and POSTing {"issuer": ...}.
• Version bump 2.4.0 → 2.5.0 (version.py + pyproject.toml) and a 2.5.0 CHANGELOG entry.

Dependency / rollout

Important

Do not publish/release the package until the toaster backend endpoint POST /v1/admin/user/remove_mfa is deployed. This PR is the SDK client side only; unit tests mock the request layer, so it builds and tests independently.

The user must belong to the app associated with the configured X-Magic-Secret-Key; otherwise the backend rejects the request.

Test Plan

• test_remove_mfa_by_public_address added — asserts the request is made to v1_user_remove_mfa with the real derived issuer
• Full unit suite passes locally (112 passed, Python 3.11)
• CI tox matrix (py311/py312/py313) + lint green on this PR
