feat(dashboard): employee data flow graph

[subomi]

Summary

• Adds an employee-level data flow graph to Insights > Employee Detail, showing MCP usage from origin through client, server, and tool nodes.
• Adds telemetry.getEmployeeDataFlowGraph plus generated SDK and React Query support for typed graph nodes and weighted edges.
• Aggregates ClickHouse telemetry into the top 100 path tuples, then builds deduped nodes and collision-safe edges in Go with call, success, and failure counts.
• Captures hook hostname as the gram.hook.hostname attribute and uses it as the graph origin.

Test plan

• go test ./server/internal/telemetry -run 'Test(BuildEmployeeDataFlowGraph_DoesNotCollideEdgesWhenLabelsContainDelimiter|GetEmployeeDataFlowGraph)' -count=1
• Click-test Insights > Employee Detail against live telemetry and verify graph counts/layout.

CleanShot.2026-05-29.at.1.49.40.mp4

Fixes AGE-2503.

P2: Missing bloom filter indexes for `endpoint_os` and `endpoint_arch`. Every other materialized column in this table has a corresponding index. If these columns will be used in WHERE clauses, the missing indexes will hurt query performance on large datasets.</violation>
