fix(config): treat blank env values as unset so the proxy neither crash-loops nor silently drops a guardrail (#46341)
* fix(config): treat blank numeric env values as unset instead of crashing at import

A numeric knob exported as an empty string, which is what a Helm value: "" or an
emptied .env line produces, raised ValueError inside litellm/constants.py and the
proxy crash-looped before serving traffic. Every int(os.getenv(...)) and
float(os.getenv(...)) in constants.py now goes through get_env_int / get_env_float,
which treat blank as unset and fall back to the default with a warning on garbage.

* fix(guardrails): treat blank litellm_params values as unset so the guardrail still loads

A guardrail whose litellm_params read os.environ/X resolves X to "" when the
variable is exported but empty. Pydantic rejected "" for bool and typed fields
such as default_on and fail_on_error, the boot log reported the guardrail as
skipped and the proxy came up without it. A before-validator on BaseLitellmParams
now drops blank string values so each field takes its default, and the
default_on shortcut in LitellmParams treats a blank value as False.

* fix(config): warn once about an unparsable numeric env value so logging cannot recurse

The LiteLLM loggers' filter reads MAX_STRING_LENGTH_STDOUT_LOG and MAX_BASE64_LENGTH_STDOUT_LOG through get_env_int on every record. Warning about a garbage value from inside that read re-entered the filter, so every log call raised RecursionError. The value is now marked as reported before the warning is logged, which also stops per-record readers from repeating it. get_env_int_or_none and the new get_env_float_or_none share the same parser

* fix(config): treat blank values as unset for the remaining import-time numeric knobs

LITELLM_MAX_STREAMING_DURATION_SECONDS, REALTIME_WEBSOCKET_MAX_MESSAGE_SIZE_BYTES, a whitespace CLI_JWT_EXPIRATION_HOURS, LITELLM_CONFIG_PARAM_CACHE_TTL_SECONDS, the agent health check timeouts and the Prisma reconnect knobs still crashed the proxy at boot when blank. A blank or unparsable REQUEST_TIMEOUT no longer counts as explicitly set, so chat completion() keeps its 600s fallback

* fix(guardrails): map blank litellm_params to the field default so PATCH can still clear a value

Dropping blank keys before validation made PATCH /guardrails/{id} with api_base "" a silent no-op. Blank values of optional fields now resolve to the field default and stay in the set fields, so the PATCH clears the stored value. Required fields and unknown keys keep the value as given

* test: cover proxy numeric knobs in-process and expect no warning for a blank Straiker api_version

The three proxy import-time numeric knobs move into litellm/constants.py so the existing in-process blank-env test covers them, replacing the subprocess test. A blank api_version now means unset, so the Straiker test asserts the key-prefix version with no warning.

* fix(guardrails): keep LitellmParams kwargs typed without adding argument-type errors
