CW-580: BIP39 Wallets Shared Seed Implementation: "One Seed - Multiple Wallets" (#1307) * feat: Implement creating new BIP39 wallet with same seed used for other owned BIP39 wallets * feat: Use same seed for BIP39 Wallets * Update pre_existing_seeds_page.dart * Feat: BIP39 Same seed wallet creation using the Common Parent Wallet Strategy * feat: Finalize implementing preexisting seeds * feat: Implement shared bip39 wallet seed for Bitcoin wallet type * feat: Implement shared bip39 wallet seed for Litecoin wallet type * feat: Implement shared bip39 wallet seed for BitcoinCash wallet type * feat: Implement shared bip39 wallet seed for Nano wallet type, although disabled entry for now * fix: Remove non bip39 seed wallet type from listing * feat: Implement grouped and single wallets lists in wallets listing page and implement editing and saving group names * fix: Issue where the ontap always references the leadwallet, also make shared seed wallets section header only display when the multi wallet groups list is not empty * fix: Add translation and adjust the way the groups display * feat: Activate bip39 as an option for creating Nano wallet types * fix: Handle edgecase with creating new wallet with group address, handle case where only bip39 derivation type is allowed with child wallets, activate nano wallet type for shared seed * chore: Modify the UI to fit adjustment made on figma * fix: Disposed box triggering error in hive and causing wallet list view to display error * fix: Switch wallet groups title in wallets list page and also fix issue with renaming groups * Update lib/reactions/bip39_wallet_utils.dart [skip ci] Co-authored-by: Omar Hatem <omarh.ismail1@gmail.com> * Update lib/router.dart [skip ci] Co-authored-by: Omar Hatem <omarh.ismail1@gmail.com> * fix: Review fixes: Combine New Wallet Page Type arguments into a single model * fix: Review fixes: Add failure guard when fetching mnemonic for selected wallet in pre-existing wallets page * fix: Review fixes - Add loading indicator when mnemonic is being selected for wallet * fix: Review fixes - Modify variable name to avoid clashes * fix: Review fixes - Access WalletManager through dependency injection instead of service location * fix: Review fixes - Add testnet to convertWalletInfoToWalletlistItem function, and adjust according where used * fix: Review fixes - Add walletPassword to nano, tron and wownero wallets and confirm it is properly handled as it should be * fix: Remove leadWallet, modify filtering flow to reflect this and not depend on leadWallet, and adjust privacy settings * fix: Review Fixes - Modify restore flow to reflect current nature of bip39 as default for majority of wallet types * fix: QA Fixes - Modify preexisting page to display wallet group names if set, and display them in incremental order if not set * fix: Add wallet group description page and rename pre-existingseeds page to wallet group display page * fix: Product Fix - Rename pre-existing seeds file name to wallet group display filename * fix: Product fix - Separate multiwallets groups from single wallets and display separately * fix - Product Fix - Add empty state for wallet group listing when creating a new wallet, adjust CTAs across buttons relating to the flow also --------- Co-authored-by: Omar Hatem <omarh.ismail1@gmail.com>
