feat(workflows): add dispatch, view, enable and disable subcommands (#952)

## Summary

- Add `tea actions workflows dispatch` to trigger `workflow_dispatch` events with `--ref`, `--input key=value`, and `--follow` for log tailing
- Add `tea actions workflows view` to show workflow details
- Add `tea actions workflows enable` and `disable` to toggle workflow state
- Rewrite `workflows list` to use the Workflow API instead of file listing
- Remove dead `WorkflowsList` print function that used `ContentsResponse`
- Update `CLI.md` and `example-workflows.md` with usage documentation and examples

## Motivation

Enable re-triggering specific workflows from the CLI, which is essential for AI-driven PR flows where a specific workflow needs to be re-run after pushing changes.

Leverages the 5 workflow API endpoints already supported by the Go SDK (v0.24.1) from go-gitea/gitea#33545:
- `ListRepoActionWorkflows`
- `GetRepoActionWorkflow`
- `DispatchRepoActionWorkflow` (with `returnRunDetails` support)
- `EnableRepoActionWorkflow`
- `DisableRepoActionWorkflow`

## New commands

\`\`\`
tea actions workflows
├── list          (rewritten to use Workflow API)
├── view <id>     (new)
├── dispatch <id> (new)
├── enable <id>   (new)
└── disable <id>  (new)
\`\`\`

### Usage examples

\`\`\`bash
# Dispatch workflow on current branch
tea actions workflows dispatch deploy.yml

# Dispatch with specific ref and inputs
tea actions workflows dispatch deploy.yml --ref main --input env=staging --input version=1.2.3

# Dispatch and follow logs
tea actions workflows dispatch ci.yml --ref feature/my-pr --follow

# View workflow details
tea actions workflows view deploy.yml

# Enable/disable workflows
tea actions workflows enable deploy.yml
tea actions workflows disable deploy.yml --confirm
\`\`\`

## Test plan

- [x] `go build ./...` passes
- [x] `go test ./...` passes
- [x] `go vet ./...` passes
- [x] `make lint` — 0 issues
- [x] `make docs-check` — CLI.md is up to date
- [x] Manual test: `tea actions workflows list` shows workflows from API
- [x] Manual test: `tea actions workflows dispatch <workflow> --ref main` triggers a run
- [x] Manual test: `tea actions workflows view <workflow>` shows details
