fix(wallet): coordinate activation through shared sdk path

[CharlVS]

Summary

• force-refresh activation checks in CoinsRepo before enabling assets so the app does not act on stale activation cache state
• route app-side asset activation through ensureAssetActivated so concurrent or already-active requests reuse the shared SDK coordination path instead of failing and falling back unnecessarily
• roll the sdk submodule to merged dev commit 877bb57, which contains the TRX market-data and activation-deduplication fixes from SDK PR Clear MA series from chart at coin change #340

Test plan

• ran dart format on lib/bloc/coins_bloc/coins_repo.dart
• checked lints for lib/bloc/coins_bloc/coins_repo.dart
• did not rerun full app runtime validation in this step

if (explorerUrl.isEmpty || explorerTxUrl.isEmpty) return '';

Restore tx explorer fallback when pattern is missing

Returning '' when explorerTxUrl is empty breaks explorer actions for assets whose protocol omits txPattern (which are currently mapped to empty strings in asset_coin_extension.dart). Callers like viewHashOnExplorer() and the transaction details "View on explorer" button still pass this result directly to launchURLString, so clicking the link throws instead of opening an explorer page. The previous behavior still produced a URL from the base explorer, so this is a user-facing regression for those assets.
