feat(wallet)_: add backend support for wallet reload functionality

- Added `reloadAccountTokens` method to `Controller`, `AccessInterface`, and `Module` in `wallet_section` to trigger wallet reload.
- Updated `view` in `wallet_section` to handle new properties `isAccountTokensReloading` and `lastReloadTimestamp`.
- Emitted `SIGNAL_WALLET_ACCOUNT_TOKENS_REBUILT` with a timestamp in `service_token`.
- Implemented `restartWalletReloadTimer` RPC in `backend`.

resolves: #13652
