Workflows: Add UI for taskmaestro workflows

Discover taskmaestro workflows under ~/.taskmaestro/workflows/ and surface
them as a "Workflows" collection in the project tree alongside Scripts.
Each workflow's task input schema is auto-generated by introspecting the
Pydantic models via a Python helper (rips.taskmaestro_helper) and rendered
as PDM field bindings - scalars for str/int/float/bool, and PdmPtrField
pickers for fields typed as rips.Case / rips.WellPath / rips.View.

The Run button on a RimWorkflow writes input.yaml from current bindings
(rips object references serialized as __resinsight_ref__ maps), spawns
the helper's run subcommand, and streams output to a modeless log dialog.
The helper resolves __resinsight_ref__ markers back to live rips objects
via the running ResInsight's gRPC server before driving taskmaestro.
