feat(console):Add persistent instance deregistration support in Console v3

[Wyhhhh24]

Please do not create a Pull Request without creating an issue first.

What is the purpose of the change

Add persistent instance deregistration support for Console v3 Naming service detail.
Previously, Console v3 only supported listing and updating service instances, but users could not deregister persistent instances directly from the Console UI. This change adds the missing delete capability for persistent instances (ephemeral=false) while explicitly keeping ephemeral instances out of scope, following the maintainer guidance.
Fixes #14980

Brief changelog

• Add DELETE /v3/console/ns/instance in Console instance controller
• Restrict Console delete operation to persistent instances only, and reject ephemeral=true requests explicitly
• Extend Console instance handling chain with removeInstance:
  • InstanceProxy
  • InstanceHandler
  • InstanceInnerHandler
  • InstanceRemoteHandler
  • InstanceNoopHandler
• Use naming remove logic in inner mode and maintainer deregister logic in remote mode
• Add frontend delete support in console-ui-next
• Show delete action only for persistent instances in service detail page
• Add delete confirmation dialog, success toast, refresh handling, and pagination fallback
• Add zh-CN / en-US i18n messages
• Add focused backend unit tests for delete flow and ephemeral rejection

Verifying this change

• Confirmed UI only renders delete action for ephemeral=false
• Confirmed frontend delete request uses Console API boundary: /v3/console/ns/instance
• Confirmed backend controller rejects ephemeral=true delete requests
• Confirmed delete chain is wired through proxy, handler, inner, remote, and noop implementations
• Confirmed delete behavior keeps existing Console default semantics when ephemeral is omitted
• Confirmed focused backend unit tests cover:
  • persistent instance delete success
  • default persistent delete path
  • ephemeral instance delete rejection
  • proxy / inner / remote delete delegation

Follow this checklist to help us incorporate your contribution quickly and easily:

• Make sure there is a Github issue filed for the change (usually before you start working on it). Trivial changes like typos do not require a Github issue. Your pull request should address just this issue, without pulling in other changes - one PR resolves one issue.
• Format the pull request title like [ISSUE #123] Fix UnknownException when host config not exist. Each commit in the pull request should have a meaningful subject line and body.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Write necessary unit-test to verify your logic correction, more mock a little better when cross module dependency exist. If the new feature or significant change is committed, please remember to add integration-test in test module.
• Run mvn -B clean package apache-rat:check spotbugs:check -DskipTests to make sure basic checks pass. Run mvn clean install -DskipITs to make sure unit-test pass. Run mvn clean test-compile failsafe:integration-test to make sure integration-test pass.
