refactor(runtime): Re-home endpoint wiring package

[leumor]

Summary

• move the endpoint and TMCI wiring cluster from network.crypta.node to network.crypta.runtime.endpoints
• update node/admin/http callers plus the five direct endpoint tests to use the new package
• carry the existing SpotBugs exclusions forward so the package move stays tooling-neutral
• keep the move behavior-preserving, with only the small compile fix needed to preserve TMCI peer flush access

Notes

• no new Gradle module
• no endpoint lifecycle redesign
• no new endpoint SPI
• node.useralerts remains untouched in this PR

Testing

• ./gradlew compileJava compileTestJava
• ./gradlew test --tests 'network.crypta.runtime.endpoints.*' --tests 'network.crypta.node.NodeClientCoreTest' --tests 'network.crypta.node.NodeClientCoreTransferPolicyTest' --tests 'network.crypta.runtime.admin.LegacyQueueSupportPortTest' --tests 'network.crypta.runtime.admin.LegacyQueuePagePortTest' --tests 'network.crypta.runtime.admin.LegacyQueueMutationPortTest' --tests 'network.crypta.runtime.admin.LegacyQueueInsertPortTest' --tests 'network.crypta.runtime.admin.LegacyQueueDownloadPortTest' --tests 'network.crypta.runtime.admin.LegacyQueueCompletionPortTest' --tests 'network.crypta.clients.http.CoreHttpShellRuntimeSupportTest' --tests 'network.crypta.clients.http.SimpleToadletServerTest'
• ./gradlew clean spotbugsMain
