feat: Add prioritized coins display for unauthenticated users

[DeckerSU]

This PR adds priority-based sorting for the asset list displayed to unauthenticated users on the wallet page. Priority coins (BTC, KMD, ETH, BNB, LTC, DASH, ZEC, DOGE) are now displayed first in a specified order, followed by all other coins sorted alphabetically.

This change improves user experience by ensuring that when users first launch the wallet, they immediately see familiar and popular cryptocurrencies (such as Bitcoin, Ethereum, Komodo) instead of less-known assets that might appear first in alphabetical order (e.g., "1inch", "Aave", etc.). This makes the onboarding experience more intuitive and helps users quickly identify well-known assets.

Changes

1. Priority Tickers Configuration

• Added unauthenticatedUserPriorityTickers constant in lib/app_config/app_config.dart
• Defined as a List<String> to preserve order (BTC, KMD, ETH, BNB, LTC, DASH, ZEC, DOGE)
• Order of coins in this list determines their display order

2. Asset List Sorting Logic

• Modified AssetsList._groupAssetsByTicker() in lib/views/wallet/wallet_page/common/assets_list.dart
• Implemented priority-based sorting for grouped asset view:
  • Priority tickers appear first, maintaining the order from unauthenticatedUserPriorityTickers
  • Non-priority tickers follow, sorted alphabetically

Behavior

For unauthenticated users (AuthorizeMode.noLogin and AuthorizeMode.hiddenLogin):

1. Assets are grouped by ticker symbol
2. Priority ticker groups appear first in the order: BTC → KMD → ETH → BNB → LTC → DASH → ZEC → DOGE
3. Remaining ticker groups are displayed alphabetically after priority groups

For authenticated users:

• No changes - existing sorting logic remains unchanged (balance and priority-based sorting)

Confirm functioning as explained. Coins to be included in this list may be up to debate, and modified in future, but this PR functionally adds the described changes.
