[plan] Split `gateway_logs.go` by concern

[github-actions]

Objective

Split pkg/cli/gateway_logs.go (1,066 lines) into concern-aligned files.

Context

Discussion: #26221

This file mixes four independent concerns: type definitions, RPC message parsing, gateway log parsing, MCP tool-call extraction, and aggregation.

Approach

• gateway_logs_types.go — all type/struct definitions
• gateway_logs_rpc.go — parseRPCMessages, findRPCMessagesPath, buildToolCallsFromRPCMessages
• gateway_logs_parsing.go — parseGatewayLogs, processGatewayLogEntry, getOrCreateServer, getOrCreateTool
• gateway_logs_aggregation.go — calculateGatewayAggregates, buildGuardPolicySummary
• gateway_logs_mcp.go — extractMCPToolUsageData

Files to Modify

• Split: pkg/cli/gateway_logs.go
• Create: pkg/cli/gateway_logs_types.go
• Create: pkg/cli/gateway_logs_rpc.go
• Create: pkg/cli/gateway_logs_parsing.go
• Create: pkg/cli/gateway_logs_aggregation.go
• Create: pkg/cli/gateway_logs_mcp.go

Acceptance Criteria

• Original gateway_logs.go is ≤ 300 lines (or removed if entirely replaced)
• Each new file is ≤ 300 lines
• make build && make test-unit pass without errors
• make fmt && make lint pass without errors
