* feat(otel): add SigNoz preset for OpenTelemetry v2

Adds the signoz callback (OTLP/HTTP exporter, GenAI vocabulary, key and team level dynamic ingestion endpoint and key) as an OpenTelemetry v2 preset, with the preset factory accepting the allow_missing_credentials kwarg the V2 registry always passes so construction no longer falls back silently to legacy OpenTelemetry. Ships the deterministic tests/integration/observability/test_signoz_delivery.py audit suite

Absorbs the work from https://github.com/BerriAI/litellm/pull/38206

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* refactor(otel): drop explanatory comments from the SigNoz preset

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* style(types): keep signoz dynamic param lines within ruff format width

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(signoz): assert the missing-endpoint boot path directly instead of in an except block

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* chore(ui): regenerate schema.d.ts for the signoz health service

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(otel): allowlist SigNoz key/team endpoints and route keyless collectors without the operator key

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(otel): terminate the SigNoz shutdown cell before the flush and drop test docstrings

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* refactor(otel): keep the shared tenant routing untouched and require an ingestion key for SigNoz key/team endpoints

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(otel): warn about a keyless SigNoz team endpoint from the header resolver so the shared cache actually reaches it
