Get Observability Tools

Distinct tool_name values within the requested filter scope.

Powers the FE TraceHeader tool-filter dropdown. Without this endpoint, the FE has to derive available tools from spans the user has manually expanded — most users never expanded enough sessions to see the filter populate. Returns a flat sorted list capped server-side.

Same filter precedence as /sessions (agent_id wins; else (project_key_id, client_id); else fleet-wide). Default range is the last 24h, matching the rollup window.
