Fix star/read buttons: _id string vs number type mismatchclaude/agents-file-mobile-stars-2nj6y

The Go API returns _id as a JSON string (due to the `json:",string"` tag
on Item.Id), but the frontend compared it with === against numbers from
parseInt(). String "5" === number 5 is always false in JS, so toggleStar,
mark-as-read, and keyboard shortcuts silently did nothing.

Fix:
- Coerce _id to Number() when items are loaded from the API
- Use Number() coercion in all store.items.find() comparisons as defense
- Revert the CSS touch-target changes (the issue was never about size)
- Add a regression test with string _id to prevent reintroduction
