Subject: [PATCH 2/7] refactor(tron-wallet-snap): remove remaining Network and
 scope casts

- Assert supported networks where data enters the snap: manifest scopes,
  AssetsController assets, Token API filtering and TrackTransaction
  background event params.
- Carry the validated `Network` type instead of re-casting: sign
  renderers take `TronWalletKeyringRequest`, send uses `asset.network`,
  staking and zero-balance assets use `getAssetNetwork`.
- Add `TronKeyringAccount` with `scopes: Network[]` for stored accounts;
  it remains assignable to the emitted `KeyringAccount`.
- Build CAIP asset types from `Network` instead of `TrxScope`.
- Add a lint rule banning casts to `Network` or `TrxScope` in the Tron snap.

 ### Changed
 
+- Reject scopes that are not supported Tron networks instead of accepting them unchecked ([#394](https://github.com/MetaMask/internal-snaps/pull/394))
+  - `onAmountInput`, `confirmSend`, `claimUnstakedTrx`, `claimTrxStakingRewards` and `resolveAccountAddress` now throw an `InvalidParamsError` for an asset or scope on an unsupported chain.
+  - Assets returned by the AssetsController on an unsupported chain now throw instead of being mapped.
 - Render the confirmation "Estimated changes" section with the shared `EstimatedChanges` component from `@metamask/snap-networks-utils` ([#396](https://github.com/MetaMask/internal-snaps/pull/396))
   - Estimated changes from the previous scan now stay visible while a confirmation re-scans, instead of showing a loading skeleton

Subject: [PATCH 4/7] refactor(tron-wallet-snap): derive client network map
 from Object.values(Network)

The config structs validate the clients' baseUrls as
record(NetworkStruct, UrlStruct), so keys are guaranteed to be supported
networks. Iterating Object.values(Network) keeps that typing end to end,
removing the Object.entries key-widening that previously forced a runtime
isSupportedNetwork guard (and, before this PR, an 'as Network' cast).
