feat(oci-cloud-mcp-server): enhancements to improve quality and efficiency

[gebhardtr]

Description

The goal of this PR is to make invoking the OCI Python SDK as precise/restricted as we can via JSON but as natural as code for the LLM.

Add new tools that:

• List clients (obviating the need to rely on the model's awareness of the SDK -- should work better with smaller models)
• filter operations (reduce context usage)
• better expose operation details (expected_kwargs etc, to improve model understanding and reduce round-trips)
• Improve type coercion (help the model invoke the operation correctly the first time)

Fixes # (issue)

There might a bug but I can't be sure, I tried creating a bucket using the cloud mcp server and it gave me a result saying it created the bucket but turns out there was no bucket named xx and with ocid xx. It printed out a fake ocid.
I was using:
oca/grok4 model with 128K context

Tested cloud mcp server with gpt 5.4 mode, looks good!

Not sure but should we add enable/disable and scale(used for autoscaling) here too?
