fix(scim): add type attribute to ScimEmail (#9690)

# Which Problems Are Solved

- SCIM PATCH operations for users from Entra ID for the `emails`
attribute fails due to missing `type` subattribute

# How the Problems Are Solved

- Adds the `type` attribute to the `ScimUser` struct and sets the
default value to `"work"` in the `mapWriteModelToScimUser()` method.

# Additional Changes

# Additional Context

The SCIM handlers for POST and PUT ignore multiple emails and only uses
the primary email for a given user, or falls back to the first email if
none are marked as primary. PATCH operations however, will attempt to
resolve the provided filter in `operations[].path`.

Some services, such as Entra ID, only support patching emails by
filtering for `emails[type eq "(work|home|other)"].value`, which fails
with Zitadel as the ScimUser struct (and thus the generated schema)
doesn't include the `type` field.

This commit adds the `type` field to work around this issue, while still
preserving compatibility with filters such as `emails[primary eq
true].value`.
