🪢 feat: Langfuse Fanout Connection Setting (#14108)
* feat: encrypt tenant Langfuse secret in admin config

Add generic per-field secret encryption to the admin config layer: registered
secret paths (langfuse.secretKey) are encrypted with encryptV3 on write and a
non-secret fingerprint companion is stored. Admin config reads (base + per
principal) redact registered secrets so they are never returned; the fingerprint
is kept so the UI can show which key is configured.

The Langfuse fanout read path decrypts the tenant secret before export. Adds
secretKeyFingerprint to langfuseConfigSchema and tests for the encrypt/redact
policy.

* fix(api): secure admin config secret handling

* fix(api): preserve encrypted langfuse config secrets

* fix(api): couple config secret fingerprint deletion

* fix(api): read langfuse fanout collector url from env

* fix(api): display langfuse secret key hint

* fix(api): remove langfuse secret fingerprint breadcrumbs

* fix(api): use langfuse destination keys for tenant config

* fix(api): remove langfuse config compatibility fallbacks

* refactor(api): simplify langfuse secret helpers

* refactor(api): simplify langfuse config secret handling

* feat: in-app Langfuse connection settings panel

Add a discoverable, admin-gated Langfuse connection panel inside LibreChat
Settings (Dify-style): enable toggle, host, public key, masked write-only secret,
configured-key fingerprint, and a test-connection action. Backed by a dedicated
/api/admin/langfuse/connection endpoint that encrypts the secret at rest, returns
metadata plus fingerprint on read, and validates credentials. Builds on the
per-field encryption and fanout decrypt from the langfuse-config-encryption branch.

* refactor: align Langfuse secret field to CustomUserVars pattern

Use the established SecretInput plus Set/Unset state pill (com_ui_set/com_ui_unset)
from the MCP CustomUserVars UI for the saved-secret state, instead of a bespoke
masked input.

* fix: drop em dash from saved-secret placeholder

* feat: show loading state on Langfuse test connection button

* feat: gate in-app Langfuse settings on fanout config and admin role

* test: align Langfuse connection spec with SecretInput refactor

* feat(langfuse): refine tenant connection controls

* fix(admin): refine Langfuse connection verification

* fix(langfuse): refine tenant connection settings

* fix(langfuse): simplify export enablement controls

* fix(langfuse): validate tenant export configuration

* fix(langfuse): align startup fanout gate

* fix(admin): time out Langfuse verification

* fix(ui): rename Langfuse connection setting

* fix(admin): enforce Langfuse config capability

* feat(langfuse): require explicit tenant export activation

* feat(langfuse): support single-tenant connection settings

* fix(i18n): remove obsolete integrations label

* fix(langfuse): authenticate ingestion verification

* fix(langfuse): validate public key independently

* fix(langfuse): localize connection errors

* perf(config): skip Langfuse checks for non-admins

* fix(langfuse): preserve trace sampling for feedback

* test(langfuse): fix feedback sampling fixture

* fix(langfuse): align secret preview field

* fix(langfuse): harden connection settings state

* fix(langfuse): preserve trace destination state

* fix(langfuse): enforce tenant-wide routing invariants

* fix(langfuse): preserve verified connection invariants

* fix(langfuse): preserve stable project identity

* fix(langfuse): warm project identity asynchronously
