chore: filter out Tron staking special assets

[ulissesferreira]

Description

As part of Tron's staking experience improvements we will be sending more special assets from the Snap to the Extension. These special assets are not tradeable tokens and should be filtered out from selectors like we already do for Staked TRX for example.

This PR:

• Adds the new special assets that should be ignored by the selectors
• Renames the variables that deal with this logic to be more inclusive of assets that are not resources (only Energy and Bandwidth are resources)

CHANGELOG entry: null

Closes: NEB-582, NEB-584, NEB-586

Manual testing steps

All existing Tron functionality should remain unchanged

Note

Medium Risk
Changes token/asset filtering for Tron by excluding additional Snap-provided “special assets” from sorted asset lists and unified multichain token lists, which could inadvertently hide tokens if symbols collide or filtering is misapplied. Scope is contained to Tron selectors/utilities and related UI consumers, with broad test updates.

Overview
Introduces a broader Tron “special assets” concept (resources + staking lifecycle assets) and filters these virtual tokens out of user-facing asset/token lists.

Renames and expands the Tron selector from selectTronResourcesBySelectedAccountGroup to selectTronSpecialAssetsBySelectedAccountGroup (and TronResourcesMap to TronSpecialAssetsMap), adding mappings for trxReadyForWithdrawal, trxStakingRewards, and trxInLockPeriod while preserving totalStakedTrx computation.

Centralizes special-asset detection in core/Multichain/utils via isTronSpecialAsset and reuses it in selectSortedAssetsBySelectedAccountGroup, selectAccountTokensAcrossChainsUnified, and Bridge isTradableToken; updates related Earn/TokenDetails/AssetOverview hooks and tests accordingly.

E2E Test Selection:
This PR is a refactoring that renames Tron resource constants to "Tron special assets" and adds three new special asset types (TRX_READY_FOR_WITHDRAWAL, TRX_STAKING_REWARDS, TRX_IN_LOCK_PERIOD) that should be filtered out from user-facing asset lists.

Key Changes:

1. Core Multichain constants/utils: Renamed TRON_RESOURCE to TRON_SPECIAL_ASSET_SYMBOLS, added new asset types, and created isTronSpecialAsset() utility function
2. Asset selectors: Updated selectSortedAssetsBySelectedAccountGroup and selectTronSpecialAssetsBySelectedAccountGroup to filter out the new special assets
3. Bridge/Swap: Updated isTradableToken to use the new utility function for filtering non-tradable Tron assets
4. Earn components: Updated to use renamed selectors for Tron staking/unstaking flows

Tag Selection Rationale:

• SmokeTrade: The isTradableToken function used in Bridge/Swap token selection is modified. This ensures Tron special assets are properly filtered from swap/bridge token lists.
• SmokeNetworkExpansion: Tron is a non-EVM chain, and these changes affect how Tron assets are handled in the multi-chain architecture.

Not Selected:

• SmokeConfirmations: The only Tron-related test is skipped, and the changes don't directly affect confirmation flows
• SmokeAccounts: No account management changes
• Other tags: Changes are Tron-specific and don't affect other features

The changes are primarily internal refactoring with consistent behavior - the filtering logic is being consolidated and extended to cover more Tron special asset types.

Performance Test Selection:
The changes modify selectSortedAssetsBySelectedAccountGroup selector which is used for asset list rendering. A new filter operation is added to filter out Tron special assets. While this is a minor change (adding a filter call), it affects the asset loading path which could have marginal performance implications. Running @PerformanceAssetLoading will verify that asset list rendering performance is not degraded by the additional filtering logic.
