fix(console): support Zitadel Support IDP (#12619)

# Which Problems Are Solved

The backend and the new login already support the dedicated ZITADEL IdP
template
(`AddZitadelProvider`/`UpdateZitadelProvider`, `PROVIDER_TYPE_ZITADEL`,
`InstanceRolesInfo`),
but the Console does not expose it:

- A ZITADEL provider cannot be created or edited from the Console,
neither at instance nor at
organization level — it is missing from the "add provider" list in the
IdP settings.
- Providers created through the API are listed in the IdP table as
`coming soon` (the type
`@switch` has no `PROVIDER_TYPE_ZITADEL` case) and the row has no detail
route, so an existing
  provider cannot be opened.
- `InstanceRolesInfo` — the organization ID/domain pairs that drive
instance-role synchronization
  for instance-level providers — is not configurable outside the API.

# How the Problems Are Solved

- Added `ProviderZitadelComponent`
(`console/src/app/modules/providers/provider-zitadel/`),
  modeled on the generic OIDC provider component:
- Form for `name`, `issuer`, `clientId`, `clientSecret` and `scopesList`
(chip input, defaulting
to `openid`, `profile`, `email`), plus the shared
`cnsl-provider-options` block.
- On edit the client secret is optional and is only sent when the
"update client secret"
    checkbox is set.
- Reuses `cnsl-provider-next` for the callback URL, activation and "what
now" flow.
- Added the instance role mapping section, rendered only for
instance-level providers
(`serviceType === ADMIN`), since the API rejects `instance_roles_info`
on organization-scoped
ZITADEL providers. Entries are added as organization ID + organization
domain pairs and are
submitted as `InstanceRolesInfo`; both values are required and are
matched together on login.
- Added `addZitadelProvider`/`updateZitadelProvider` to `AdminService`
and `ManagementService`
  wrapping the existing gRPC calls.
- Declared the component in `providers.module.ts` and mapped
`PROVIDER_TYPE_ZITADEL` to the
`zitadel` path in `providers-routing.module.ts`, so
`/instance/provider/zitadel/...` and
  `/org/provider/zitadel/...` resolve for both create and edit.
- Added a ZITADEL tile to the "add provider" list in the IdP settings
and a
`PROVIDER_TYPE_ZITADEL` case to the IdP table;
`IdpTableComponent.routerLinkForRow` now returns
  the detail route for ZITADEL rows.

# Additional Changes

- Added the new i18n keys `IDP.CREATE.ZITADEL.TITLE`/`DESCRIPTION`,
`IDP.INSTANCEROLESINFO`,
`IDP.INSTANCEROLESINFO_DESC`, `IDP.ORGANIZATIONID` and
`IDP.ORGANIZATIONDOMAIN` to all 22
Console locale files with actual translations instead of English
fallbacks.
- The provider tile, table entry and detail header use the colored
ZITADEL logo assets
(`zitadel-logo-solo-light.svg` in the dark theme,
`zitadel-logo-solo-dark.svg` in the light
theme), consistent with the header, rather than the monochrome
`*-solo-*-icon.svg` variants.
- Additional sync roles trigger for the support IDP to behave correctly
on first login after a disable/enable cycle — where auto-linking jumps
in — but not required for the link to be established.

# Additional Context

- Closes #11825
- Part of the "Zitadel as an Identity Provider" epic #5127
- Console counterpart to the API work in #12018, #12056 (add), #12371,
#12378, #12384 (update),
#12394 (get/list), #12396 (delete), #12422 (active IdPs) and to the
login support in #12469,
  #12530 and #12568
