Fix potential memory leak in PluginViewModel flow collectors

- Replaced three separate flow collectors with a single combined flow
- Prevents potential race conditions and reduces coroutine overhead
- Uses combine() to merge pluginsEnabled, repositories, and scrapers flows
- Single collector updates UI state atomically for all three values

This ensures that flow collection is more efficient and reduces the risk
of memory leaks from multiple concurrent collectors.
