feat(workflows): add revision history, trash, UUID naming, and backup

- Store up to 50 revisions per workflow in SQLite with normalized SHA dedup
- Soft-delete workflows to trash (7-day retention) with restore and permanent purge
- Assign UUID filenames for new and duplicated workflows; show name + file in UI
- Warn on invalid YAML, unknown scripts, and plaintext secrets with save-anyway option
- Add workflow backup zip (workflows + plugins) and merge/replace restore
- Trash page, history panel on editor, and smoke test
