batches/ui: add verbose logging to pre-execution phases

Add verbose logging to TUI for batch changes pre-execution steps:
- Namespace resolution: show resolved namespace ID
- Container images: log successful preparation
- Workspace resolution: show workspace/repo counts and unsupported/ignored counts
- Cache check: show cached specs and tasks to execute
