Fix: Issue with cache handling for polyaxon run.
Fix: Honor configured timeouts in synchronous and asynchronous Python SDK requests, with a 60-second default and per-request overrides.

Enhancement: Rename tracking_timeout to tracking_flush_delay and POLYAXON_TRACKING_TIMEOUT to POLYAXON_TRACKING_FLUSH_DELAY.

New: Add authenticated connection checks for Kubernetes access and default artifact store read, write, and delete access.
Enhancement: Check connections before managed agents start syncing and report failed checks as FAILED with diagnostics.
Fix: Keep reconciliation running after agent data collection failures and redact sensitive values from API error logs.
Fix: Return structured, sanitized errors when agent data collection cannot initialize the configured artifacts store.

Enhancement: Remove RabbitMQ broker support. Redis is now the only supported scheduler broker.
