fix(otel): consolidate to single OTel SDK init at instrumentation.register hook

All three apps' instrumentation.ts files now call initOtelServerNode directly
instead of initSentryServer/initSentryServerNode, closing the startup window
where @sentry/nextjs auto-instrumentation could send unscrubbed errors before
bindAll() fires. bindOtelInstrumentation no longer calls initOtelServerNode
(SDK init belongs at app boot, binding at request scope). Orphaned sentry/
init-server*.ts files deleted; their package.json subpath exports removed.
