Add ACCESSOM3Profiling to access_models.py

[minghangli-uni]

closes #47

closes #55

Before this PR, parts of the scaling and perturbation logic reflected esm1.6 assumptions but this is hard to add or modify support for another model, say ACCESS-OM3. So this PR not only adds supports for access-om3 configs but refactors the PayuManager into an orchestrator layer only.

Now PayuManager coordinates a generic sequence - for each requested node count, it builds model-specific layout search configuration, then requests layouts from the model adaptor (ie ACCESSOM3Profiling), then constructs a perturbation block per layout via a model-defined builder and finally passes the resulting blocks to the experiment-generator layer.

So now PayuManager no longer encodes any model layout structure.

EDIT: This update breaks the existing ESM1.6 workflow. We need adjustments to bring esm1.6 adaptor into alignment with the new interface, likely in a followed-up PR.

@minghangli-uni Are you planning on adding here support for ESMF traces or will you include that later?

[minghangli-uni]

Oops, sorry I've just seen this. Yes, I'm planning to implement esmf-trace here.
