This commit switches from manylinux_2_28 to manylinux_2_34 to properly
support our C extensions that require GLIBC 2.34+ features.

Changes:
- Use manylinux_2_34 container images in cibuildwheel
- Enable auditwheel repair with manylinux_2_34 platform tag
- Add fallback to rename linux_x86_64 wheels to manylinux_2_34_x86_64 if needed
- Switch from yum to dnf for RHEL 9+ based containers

This ensures our wheels work on:
- Ubuntu 22.04+
- RHEL/CentOS 9+
- Debian 12+
- Any system with GLIBC 2.34+

The combination of proper manylinux tags and metadata fixes should
resolve all PyPI upload issues.
