feat(workspace): name SQL on initial save

[openai0229]

Related issue

Closes #2235

Summary

• Prompt for a non-empty saved SQL name on the first manual save of a Community SQL console.
• Keep cancellation as a local draft, and publish the existing console id with the chosen name and current SQL only after confirmation.
• Update the workspace tab title and saved status together after publication; later manual and automatic saves continue updating the same record without another prompt.
• Add localized EN/ZH/JA/KO/ES copy and focused saved-console lifecycle coverage.

Affected surfaces

• Frontend / Web
• Backend / API / Storage
• Database plugin / Driver
• JCEF / Desktop packaging
• CI / Build / Release
• Documentation only

Verification

• Commands and results:
  • yarn test:saved-console-lifecycle - passed.
  • yarn test:i18n - passed.
  • yarn lint - passed with zero warnings.
  • yarn run build:web:community --app_version=0.0.0 - passed; Webpack compiled successfully in 25.25 seconds.
  • git diff --check - passed.
• Manual verification:
  • Live Community backend 10825/api/system returned 200 application/json.
  • Live Community Web proxy 8889/api/system returned 200 application/json.
  • 8889/workspace returned 200 text/html.
  • The hot-reload server compiled the changed source successfully.
• UI evidence: N/A - the available browser controller reported no browser instance, so no automated click-through or screenshot was available.

Risk and compatibility

• Public API or stored data: No API or storage schema change. Initial publication includes name in the existing saved-console update payload.
• Database or driver compatibility: N/A - no database plugin or driver code changed.
• Network, privacy, or security: N/A - no new network path or data collection.
• Community / Local / Pro boundary: Community frontend only; Enterprise, Local, Pro, and Gateway sources are unchanged.
• Backward compatibility: Existing saved consoles do not prompt. Later saves keep using the same console id and existing persistence flow.

• Failure condition: First save does not prompt, cancellation publishes a record, confirmation creates a duplicate id, later saves prompt again, or the tab title/status diverges from the saved record.
• Rollback or disable path: Revert commit 35a7bb83; no data migration or backend rollback is required.
