Resolves #456

Proposed Changes

• Adds cisco.nd.nd_interfaces_workflow, a single aggregate workflow for the ten interface families currently available on develop.
• Shares fabric resolution and paginated interface inventory snapshots across resource groups to avoid redundant controller GETs.
• Separates validation and planning from mutation, including cross-family conflict detection, check-mode planning, consolidated configuration actions, and post-mutation state reconciliation.
• Preserves the standalone interface-module behavior while allowing the aggregate workflow to reuse the same models and orchestrators.
• Keeps cisco.nd.nd_interface_flow_rules outside the aggregator scope.

Why manage_vpc_pair/resources.py changes

VpcPairStateMachine already had a private _manage_override_deletions(override_exceptions) helper on develop. The shared NDStateMachine also had a same-named method. The interface-aggregator planning refactor changed the shared method to accept an optional NDStatePlan, allowing a plan calculated before mutation to be reused during execution.

That signature change exposed the pre-existing name collision as a pylint arguments-renamed failure: the shared method expects a state plan, while the vPC helper expects a list of pair identifiers that must be retained. The specialized vPC helper and its sole caller are therefore renamed to _manage_vpc_override_deletions(override_exceptions). This is a behavior-preserving compatibility change that avoids an incompatible override contract. A focused regression test verifies that override exceptions remain retained while other stale vPC pairs are deleted.

Test Notes

• Focused Python 3.11 Docker unit tests for the workflow coordinator and vPC resource service: 12 passed.
• Targeted no-smart-quotes and pylint Docker sanity checks: passed.
• Full ansible-test sanity --docker --python 3.11 -v --color --truncate 0: all 32 sanity checks passed with exit status 0.
• git diff --check: passed.

Cisco Nexus Dashboard Version

No Nexus Dashboard API behavior is changed by the vPC compatibility rename.
