CW-782: Show error report popup without cooldown (#1739)
* improve exception throwing on broken wallets
- put _lastOpenedWallet to avoid issues on windows (file is currently open by)
- don't throw corruptedWalletsSeed - instead store it inside of secureStorage
- await ExceptionHandler.onError calls where possible to makse sure that popup won't be canceled by some UI element
- adjust BaseAlertDialog to be scrollable if the text is too long
- add ExceptionHandler.resetLastPopupDate - that can be called when we want to show error report screen (bypassing cooldown)

* fix: HiveError: Box has already been closed.

* await the alerts to be sure that each one of them is being shown
fix typo in secure storage

* Update lib/core/backup_service.dart

Co-authored-by: Omar Hatem <omarh.ismail1@gmail.com>

* address comments on github

* don't store seeds in secure storage

* fix wallet password

* update monero_c
update corrupted seeds UI
prevent app from crashing when wallet is corrupted

* show alert with seeds

* Update corrupted wallet UI
Fix wallet opening cache

* remove unused code
