feat(Docker): Upgrade to PHP 8.5.0RC3 with native ext-uri support

BREAKING CHANGE: Requires PHP 8.5.0RC3

Changes:
- Update Docker base image from php:8.4-fpm to php:8.5.0RC3-fpm
- Enable ext-uri for native WHATWG URL parsing support
- Update composer.json PHP requirement from ^8.4 to ^8.5
- Add ext-uri as required extension in composer.json
- Move URL classes from Url.php85/ to Url/ directory (now compatible)
- Remove temporary PHP 8.4 compatibility workarounds

Benefits:
- Native URL parsing with Uri\WhatWg\Url class
- Better performance for URL operations
- Future-proof with latest PHP features
- Eliminates PHP version compatibility issues
