Add `RUSTFS_IDENTITY_OPENID_HIDE_FROM_UI[_<SUFFIX>]` setting that
removes a provider from the login page while keeping it fully
functional for STS AssumeRoleWithWebIdentity and site-replication.
Changes:
- Add `hide_from_ui: bool` to `OidcProviderConfig`
- Add `list_visible_providers()` that filters hidden providers
(used by console login and /v3/oidc/providers endpoint)
- Keep `list_providers()` unfiltered for site-replication/admin config
- Extract `normalize_provider_config(config) -> config` to deduplicate
field normalization (accepts the struct directly, not 18 parameters)
- Add `parse_enable_state()` helper for consistent EnableState parsing
- Plumb through admin API request structs (`#[serde(default)]`)
- Expose in `OidcConfigView` for admin GET config round-trip
- Persist via `upsert_persisted_provider_config()`
Note: adding `hide_from_ui` to the public `OidcProviderConfig` struct
is a source-level change for code constructing it with struct literals.
This is acceptable for the current pre-1.0 release cycle.
