chore: bump version to v2026.4.377 and fix dialog/redirect issues}
- Bump version from v2026.4.375 to v2026.4.377 in package.json and README.md - Cap dialog max-height to calc(100vh - 64px) to prevent dialogs from extending behind the toolbar in both Angular and React frontends - Add overflow: hidden on dialog overlay pane and React dialog paper - Remove max-height cap on .p3xr-dialog-content so content scrolls freely - Fix Angular frontend redirect to skip port 8080 (dev server) and stop stripping trailing query string characters - Move React-to-Angular redirect from index.html inline script to main.tsx with production-only guard (skip when p3xrDevMode is set)
