Describe the bug

Description

The setup/install_deps.sh script fails:

1. while installing config_explorer component because of incorrect resolution of directory path to config_explorer directory and
2. when the path to the repository contains spaces due to unquoted variables in the script

Steps to reproduce

Steps to Reproduce

1. Clone repository to a path with spaces (e.g., /path/with spaces/llm-d-benchmark)
2. Run ./setup/install_deps.sh
3. Script fails with errors about missing directories
4. Script also fails while resolving directory path to config_explorer even if there are no space characters in the path variables

Additional context or screenshots

Root Causes

1. Unquoted path variables cause word splitting
2. LLMDBENCH_INSTALLDEPS_DIR incorrectly resolves to repository root instead of setup directory
3. config_explorer installation fails due to incorrect path resolution
