feat: introduce useAssetVisibility hook and AssetsController selectors

- Add getCustomAssets, getAssetsBalance, getAssetsInfo, getAssetPreferences
  selectors for AssetsController state with unit tests
- Add useAssetVisibility hook that derives the correct AssetsController
  action (addCustomAsset / removeCustomAsset / hideAsset / unhideAsset)
  based on the token's current state
- Wire handleHideToken into MoreTokenActionsMenu behind the
  isAssetsUnifyStateEnabled feature flag (legacy TokensController path
  still runs unconditionally)
- Replace direct AssetsController.addCustomAsset calls in
  AddCustomToken and SearchTokenAutocomplete with handleAddCustomAsset
  from the hook, removing per-component account-ID lookups
- Fix assets-controller-messenger test: add missing
  NetworkController:networkAdded and NetworkController:networkRemoved
  events to the arrayContaining assertion
