fix(otel): one v2 logger owns the global provider; scope tenant OTLP creds per exporter (#30590)
* fix(otel): one v2 logger owns the global provider; scope tenant creds per exporter

The proxy published the OTel global TracerProvider before callbacks were
initialized, so no preset logger existed yet and a second generic logger was
built that won the global provider. Server spans then exported through a
different provider than the preset's gen-ai spans, orphaning the LLM span on
the preset backend. Publish after callback init and reuse the already-built
logger instead.

Separately, per-request tenant OTLP credentials were stamped onto every OTLP
exporter, leaking one backend's key onto a co-configured backend. Tag each
exporter with the preset that contributed it and apply dynamic credentials
only to the matching owner.

* fix(otel): satisfy Any-discipline on changed lines

Type the logger-selection parameter as Sequence[object] (isinstance narrows
it), cast the list[Any] global at the single call site, and pass model_copy a
typed dict[str, str] update so no changed line carries an Any value.

* fix(otel): annotate the untyped-global boundary with any-ok

select_global_otel_v2_logger consumes litellm._in_memory_loggers, a shared
List[Any] global this change does not own. A cast doesn't satisfy the
Any-discipline checker (it inspects the inner expression), and re-annotating the
global is out of scope, so mark the single boundary line any-ok.

* test(otel): cover the startup global-provider publish via injectable helper

The publish step lived inline in proxy_startup_event (a FastAPI lifespan unit
tests do not execute), so its lines were uncovered though the selection logic
was tested. Extract publish_global_otel_v2_provider, which selects the single v2
logger and publishes its provider through an injected setter, and unit-test that
the published provider is the selected logger's. proxy_server delegates to it.

* refactor(otel): select global provider from the registered owner, not a list scan

The startup publish picked the global TracerProvider by scanning
_in_memory_loggers for the first OpenTelemetryV2, re-deriving an answer the
factory already settled: the first logger built registers itself as
proxy_server.open_telemetry_logger, and every other v2 path (guardrail, identity
seeding, phase spans) routes through that owner via _registered_v2_logger. Pass
that owner into select_global_otel_v2_logger so the global provider reuses the
same logger instead of an independent, order-dependent guess; the list scan
remains the SDK-path fallback. The owner is injected at the proxy call site to
keep the helper free of hidden global reads.

* refactor(otel): type ExporterSpec.owner as an ExporterOwner enum

The owner field carried free-form strings that had to match preset callback
names. Introduce a str-based ExporterOwner enum (values equal to the callback
names, so per-request credential routing's owner==callback_name comparison still
holds) and have each preset tag its exporter with the enum member.

* refactor(otel): rename ExporterOwner.ARIZE to ARIZE_AX

Distinguish the hosted Arize AX backend from Arize Phoenix at the member level
while keeping the value 'arize' (the public callback name routing compares
against). Add a comment noting AX and Phoenix are separate backends.
