fix(idp): SAML signature algorithm (#10795)

Browse Source 
# Which Problems Are Solved

https://github.com/zitadel/zitadel/pull/10520 added the possibility to
specify the signature algorithm for SAML auth requests. After releasing,
customer noticed that the Console UI would not correctly display the
selected algorithm and that it was not used in the login V1.

# How the Problems Are Solved

- Correctly map the algorithm in the UI
- Provide the option to the idp when creating a SAML request in login V1

# Additional Changes

None

# Additional Context

- closes https://github.com/zitadel/zitadel/issues/10780
- closes https://github.com/zitadel/zitadel/issues/10792
- requires backport to v4.x
