Implement comprehensive web app API endpoint fix

- Patch origins.ts during Docker build to use window.location.origin + '/api'
- Update version to 0.1.69 to force rebuild
- Add browser compatibility check for server-side rendering
- Fix both API and uploader endpoint redirections

This addresses the root cause where web apps were hardcoded to use
https://api.ente.io instead of the local Museum server.
