docs(llm-analytics): document trace filtering and time selection

[inkeep]

Changes

This PR updates the LLM Analytics traces documentation to document the new filtering and time selection capabilities added in PostHog/posthog#52860.

Added

• New "Filter and search traces" section documenting:
  • Time range selector (preset ranges, custom ranges, sparkline selection)
  • Service name filtering
  • Property filters for span and resource attributes
  • Refresh capability
  • URL persistence for sharing filtered views

Why

PR #52860 added a logs-style frontend for tracing with time selectors and filters. These are significant UI improvements that help users navigate and analyze their traces more effectively. The documentation should reflect these capabilities so users know they exist.
