fix(plugin-detail): fix React #300 crash on master-detail drill-in (hoist DetailSection early return below hooks)

[baozhoutao]

Problem

Drilling from a master record's related sub-table into a child record crashed with a minified React error #300 ("rendered more hooks than during the previous render"). The record detail page showed the orange error boundary, and refreshing bounced the user away.

Repro (showcase): Accounts list → open Northwind detail → Projects tab → click a project row → the child project detail page crashes.

Root cause

DetailSection had its all-empty early return placed before a hook:

// BEFOREif(visibleFields.length===0&&emptyCount===section.fields.length)returnnull;// ← early return
...
React.useEffect(()=>{/* virtual-scroll batching */},[vsEnabled,layoutFields.length,vsBatchSize]);// ← hook AFTER the return

When the same reconciled fiber rendered all-empty on one pass (early return → effect skipped → N hooks) and populated on the next (no early return → effect runs → N+1 hooks), the hook count changed between renders — the classic Rules-of-Hooks violation React reports as #300.

The master-detail drill-in reuses the RecordDetailView / DetailSection fiber (only objectName/recordId change via the router), and the sections flip from empty to populated, so it trips reliably.

Fix

Move the all-empty guard to run after every hook (including the useEffect), so the hook count is invariant to field/data/visibleCount. Render output is unchanged.

Verification (showcase console)

• ✅ Accounts → Northwind detail → Projects tab → Website Relaunch drill-in now renders (客户/状态/健康度/预算/负责人/已花费/日期 all show), no crash, zero console errors.
• ✅ Back-nav via breadcrumb (project → account) works, no crash.
• ✅ Inline edit + field validation ("Tax ID must look like…") + save round-trip all work.

Fixes the master-detail browse/edit/return flow reported as broken.
