fix(meshstack/manual): compute outputs from API, enable SINGLE_SELECT/STATIC inputs

[grubmeshi]

What

Adapts the meshStack Manual reference building block to the manual-outputs
change in terraform-provider-meshstack#176, and resolves the long-standing TODO that kept the SINGLE_SELECT / STATIC inputs commented out.

• Remove the version_spec.outputs block — for manual building blocks the backend derives one output per input (ManualBuildingBlockCreationModule: assignment type NONE, with SINGLE_SELECT/MULTI_SELECT/LIST translated via ManualIOTypeTranslation). With feature/azure uami vs spns #176 the provider treats version_spec.outputs as computed and reconciles it from the API, so configuring it caused "Provider produced inconsistent result after apply".
• Enable the single_select (SINGLE_SELECT) and static_note (STATIC) inputs that the TODO had disabled. The backend mirrors them (SINGLE_SELECT → STRING), so they no longer break the apply.
• e2e: supply single_select as a user input and assert its mirrored STRING output.
• Docs: update the building block README and the BBD description to reflect that every input is mirrored to an output (with type translation) and that outputs are computed.

Why the TODO is now resolved

The TODO referenced "new element single_select/static_note has appeared" in version_spec.outputs. Root cause: the backend always derived outputs from all inputs, but the provider expected the configured outputs to match exactly. Confirmed in meshfed-release:

• ManualBuildingBlockCreationModule.performImplementationTypeSpecificLogic → one output per input.
• ManualIOTypeTranslation.translateIOTypeToOutput → SINGLE_SELECT→STRING, MULTI_SELECT/LIST→CODE.

#176 adapts the provider to this (computed outputs), so the inputs can be enabled.

Dependency

Requires the meshstack provider ≥ 0.21.1 (carries #176). The module keeps the conventional ~> 0.21.0 pin (minor-pinning per AGENTS.md), which resolves to the latest patch at apply time — merge after provider v0.21.1 is released.

Validation

• terraform fmt ✅, ci/validate_modules.sh ✅, terraform validate (module root + e2e) ✅
• pre-commit hooks (fmt / docs / validate modules / whitespace) ✅

📋 Janny has linked this PR to the Feature Shipping Tracker #1344: Fix Manual Building Block Output Type Handling (SINGLE_SELECT / MULTI_SELECT).

This PR addresses DoD items 6 & 7 (reference examples updated, e2e smoke test for SINGLE_SELECT mirrored output). It was originally noted as blocked on meshcloud/terraform-provider-meshstack#176, but that planned PR was superseded by meshcloud/terraform-provider-meshstack#197 (merged, shipped as v0.21.1+) — the blocker is resolved.

[edited: corrected cross-repo PR references to use owner/repo#NNN format; clarified #176 superseded by #197]
