feat: Add approve/deny run controls to MCP and CLI (#400)
## Summary

Exposes the existing `POST /api/v1/runs/{id}/approve` and `POST
/api/v1/runs/{id}/deny` REST endpoints through the `fabro_run_interact`
MCP tool and two new top-level CLI commands (`fabro approve`, `fabro
deny`). Workflow agents are explicitly blocked from using these actions
— approval remains a human/user operation.

## What changed

**Client & tool backend** (`fabro-client`, `fabro-tool`): Added
`approve_run` and `deny_run` to `Client` and the `FabroToolBackend`
trait, implemented in `ClientBackend`. `deny_run` passes a
`DenyRunRequest` body; absent, blank, or whitespace-only reasons are
normalised to `None`.

**`fabro_run_interact` MCP tool**: Added `Approve` and `Deny` variants
to `RunInteractAction` / `ValidatedInteractAction`, and an optional
`reason` parameter (only valid for `deny`; validated and trimmed on
input). Both actions return `{ "summary": … }` using the existing shape.
The tool description is updated to list the new actions.

**Workflow-agent guard** (`fabro-workflow`): Before dispatching
`fabro_run_interact`, the handler checks
`validated.action.requires_user()`. If the action is `approve` or
`deny`, it returns an immediate `ToolError` without ever reaching the
backend, keeping the guard explicit and independent of server auth.

**CLI** (`fabro-cli`): Extracted the archive/unarchive batch loop into a
shared `run_resolved_run_batch` helper in `commands/runs/mod.rs`, then
implemented `approval.rs` using the same helper. Both commands follow
the same batch contract as archive: attempt all runs, collect per-run
errors, exit non-zero if any fail, and emit `{ "approved"/"denied": […],
"errors": […] }` in JSON mode.

**Server auth regression** (`fabro-server`): Extended
`run_tools_worker_cannot_call_user_only_non_mcp_routes` to cover `POST
/runs/{id}/deny` alongside the existing `approve` and `timeline` checks.

**Docs** (`mcp.mdx`, `cli.mdx`): Updated the `fabro_run_interact` table
entry and added approve/deny examples, plus reference sections for the
two new CLI commands.

### Plan Summary

- Add `approve_run` / `deny_run` to `Client` and `FabroToolBackend`
- Extend `fabro_run_interact` with `approve`, `deny`, and optional
`reason`
- Block workflow-agent self-approval with an early `ToolError`
- Refactor archive batch loop into shared `run_resolved_run_batch`
helper
- Add `fabro approve` and `fabro deny` CLI commands reusing that helper
- Add integration tests for CLI commands, MCP tool, and server auth
guard
