Massively expands the custom JSX widget system to support virtually all
Mantine v9 components and adds in-widget HTTP request capabilities via
a server-proxied SubFetch system.
- Whitelist ~100 Mantine components (core, all 16 charts, dates)
- Add SubFetch, SubData, ActionButton, ToggleSwitch, RefreshButton
- Add server-side subFetch tRPC mutation with same-origin + auth
- Show HTTP method warning badges in widget and admin preview
- Remove `fetch` from forbidden keywords, increase template to 50KB
- Expand bindings: Date.*, parseInt, parseFloat, Array.from, etc.
- Update AI prompt with full component reference + demo templates
react-jsx-parser auto-generates random keys on every render, causing
full remounts that reset uncontrolled Tabs to defaultValue. Fix by:
- Adding disableKeyGeneration to preserve React reconciliation
- Memoizing bindings to avoid unnecessary re-parses
- Converting TabsContainer to controlled Tabs with useState
- Validating defaultTab against actual panel values
- Clearing stale parseErrors when template/data changes
