fix: rewrite workspace page — simplified Alpine, no syntax errors

Complete rewrite of local_workspace.html with:
- flatten() as standalone function (not in Alpine component)
- wsInit() uses x-init for async loading
- No optional chaining or template literals (broader compat)
- :key uses array index to avoid undefined keys
- Simple var declarations throughout
- All modals unified with x-show toggles
