[#7617] improvement(cli): ADD Error handling and absolute path resolution in gcli.sh

[su8y]

What changes were proposed in this pull request?

• Added set -e to ensure the script exits immediately upon any command failure.

• Resolved the bin directory path to an absolute path to ensure consistent behavior regardless of the script's invocation location.

• Implemented proper error handling when the CLI_JAR is missing or not found, with a clear and informative error message.

Why are the changes needed?

Fix: #7617

Does this PR introduce any user-facing change?

• If the CLI JAR is missing, users will now see a clear error message.

• The CLI script will behave consistently, even when executed from different directories.

How was this patch tested?

• Manually ran the updated gcli.sh script with and without the CLI JAR present.

• Verified the script terminates correctly with an error when the JAR is missing.

• Confirmed the correct JAR is found and launched when present, from various working directories.

I think this clients/cli/bin/gcli.sh is not used anymore, we can actually remove this script. WDYT? @Abyss-lord

Yes, clients/cli/bin/gcli.sh is no longer in use and can be safely removed. Thanks for pointing it out.
