Fix dashboard migration discrepancies between backend and frontend implementations (use toEqual) (#110268)
**Highlights**
* **Single-version migrations**: add `targetVersion` to migrator & model, separate outputs, enforce exact version.
* **Datasource fixes**: include `apiVersion` in tests, empty-string → `{}`, preserve `{}` refs, drop unwanted defaults.
* **Panel defaults & nesting**: only top-level panels get defaults; preserve empty `transformations` context-aware; filter repeated panels.
* **Migration parity**
* V16: collapsed rows, grid height parsing (`px`).
* V17: omit `maxPerRow` when `minSpan=1`.
* V19–V20: cleanup defaults (`targetBlank`, style).
* V23–V24: template vars + table panel consistency.
* V28: full singlestat/stat parity, mappings & color.
* V30–V36: threshold logic, empty refs, nested targets.
* **Save-model cleanup**: replicate frontend defaults/filtering, drop null IDs, metadata, unused props.
* **Testing**: unified suites, dev dashboards (v42), full unit coverage for major migrations.
