fix: resolve build failures for 14 benchmarks

Fixed build issues introduced during hint removal process:

Build Infrastructure Fixes:
- XBEN-012-24, 013-24, 018-24: Updated Debian repository URLs
  (buster is EOL, using archive.debian.org)
- XBEN-084-24: Added missing 'default' network definition in docker-compose.yml

Dockerfile Path Fixes (caused by directory/file renames during hint removal):
- XBEN-051-24: Fixed CSS paths after xss → styles directory rename
- XBEN-059-24: Fixed CSS paths after xss → challenge directory rename
- XBEN-074-24: Fixed CSS paths after xss → pages directory rename
- XBEN-087-24: Fixed CSS paths after xss → styles directory rename
- XBEN-089-24: Fixed app directory paths
- XBEN-090-24: Fixed app directory paths
- XBEN-091-24: Fixed app directory paths
- XBEN-093-24: Fixed app directory paths
- XBEN-094-24: Fixed app directory paths
- XBEN-100-24: Fixed app directory paths

Added Build Testing Tools:
- test_all_builds.sh: Parallelized script to test all 104 benchmarks
- test_failed_builds.sh: Iterative testing for failed builds only
- Updated .gitignore to exclude build artifacts

Result: All 104 benchmarks now build successfully ✓
