fix: manage root CA for LDAP IdPs correctly (#9517)

# Which Problems Are Solved

#9292 did not correctly change the projection table to list IdPs for existing ZITADEL setups.

# How the Problems Are Solved

Fixed the projection table by an explicit setup.

# Additional Changes

To prevent user facing error when using the LDAP with a custom root CA as much as possible, the certificate is parsed when passing it to the API.

# Additional Context

- Closes https://github.com/zitadel/zitadel/issues/9514
