Optimize bench server for performance benchmarking

Refactors the bench_server to minimize allocations and output, using static/pre-serialized responses and minimal logging for accurate HTTP benchmarking. Updates dependencies to enable simd-json and disables tracing and swagger-ui by default for the benchmark. Improves server internals for better parallelism and disables request logging unless the tracing feature is enabled. Adds new workspace members and custom release/bench profiles for maximum performance.
