test/e2e: optimize e2e test time by replacing sleeps with TCP readiness checks (#5223)
Replace the fixed 500ms sleep after each frps startup in RunProcesses with a TCP dial-based readiness check that polls the server bind port. This reduces the e2e suite wall time from ~97s to ~43s. Also simplify the RunProcesses API to accept a single server template string instead of a slice, matching how every call site uses it.
