fix(activation): add assets deactivation state updates and silently activate coins needed for NFT

[takenagain]

Fixes the following issues:

• Deactivating a coin in the "Add Assets" page does not reflect on the main wallet page.
• Deactivated NFT coins reappearing after deactivation (e.g. AVAX, FTM, BNB, ETH).
• Possible duplication of coins in the "Add Assets" page when filtering and sorting. This could happen because the legacy usdPrice and address fields were added to the Coin model props for backwards-compatible UI/state updates.
• Filters out NFT_ coins from the private key export list

Summary by CodeRabbit

• Refactor

  • Improved code formatting and readability across several areas of the app.
  • Simplified method signatures and removed unused parameters for cleaner code.
  • Adjusted the order of state updates for more responsive UI during coin removal.
  • Updated activation methods to allow optional addition to wallet metadata and notification control.

• Style

  • Unified and streamlined code style for better maintainability and consistency.

Walkthrough

This change introduces an optional addToWalletMetadata parameter to the activateAssetsSync and activateCoinsSync methods in CoinsRepo, allowing control over wallet metadata updates during activation. Related refactoring and formatting improvements were made in coins_manager_bloc.dart and nft_main_repo.dart, with minor logic adjustments for coin activation and removal.

Changes

Cohort / File(s)	Change Summary
CoinsRepo Activation & Deactivation Logic lib/bloc/coins_bloc/coins_repo.dart	Added optional addToWalletMetadata parameter (default true) to activateAssetsSync and activateCoinsSync methods; conditional wallet metadata update; deactivation disables coin RPC calls but still broadcasts state changes.
Coins Manager Bloc Refactor & Formatting lib/bloc/coins_manager/coins_manager_bloc.dart	Refactored for improved readability and formatting; removed unused parameters from _tryActivateCoin and _tryDeactivateCoin; reordered state emission and async deactivation in coin removal; no functional logic changes.
NFTs Repo Activation Call Update lib/bloc/nfts/nft_main_repo.dart	Reformatted constructor; updated _activateParentCoins to call activateCoinsSync with notify: false and addToWalletMetadata: false, changing activation behavior for parent coins.

Poem

A hop, a skip, a wallet tweak—
Coins now know just what to seek.
Metadata’s optional, oh what fun,
Activation’s smarter, the work is done!
With code refactored, neat and bright,
This bunny’s hopping with delight.
