Cherry-picking commits from main to release/8.0.0 for PR #31838

[runway-github]

• feat: add enhanced display for approved transaction for Non EVM networks (feat: add enhanced display for approved transaction for Non EVM networks cp-8.0.0 #31838)

Description

This pull request enhances the handling and display of unlimited token
approval transactions across the app. It introduces a new
isUnlimitedApproval property to the transaction display data, updates
the logic to detect and label unlimited approvals, and ensures that UI
components and tests reflect these changes. The update also includes
comprehensive unit tests for the new logic.

Unlimited Token Approval Detection and Display:

• Added isUnlimitedApproval to the MultichainTransactionDisplayData
  interface and implemented logic in useMultichainTransactionDisplay to
  set this flag for token approval transactions with amounts above 1e15.
  The transaction title for approvals is also updated to include the token
  unit if available.

UI and Rendering Updates:

• Updated MultichainTransactionDetailsSheet and
  MultichainTransactionListItem components to use the
  isUnlimitedApproval flag. When true, these components display
  "Unlimited " instead of the raw approval amount, ensuring clarity
  for the user.

Testing Improvements:

• Added and updated tests for both the hook
  (useMultichainTransactionDisplay) and the UI components to verify
  correct detection and display of unlimited approvals, including edge
  cases and title formatting.

Dependency Update:

• Bumped @metamask/tron-wallet-snap dependency version from 1.26.0
  to 1.27.0 in package.json.

Note

Low Risk
Display-only changes to multichain transaction formatting with new
unit tests; no auth, signing, or transaction execution logic is
modified.

Overview
Fixes broken transaction UI when non-EVM (e.g. TRON TRC20) approvals
carry very large allowance values by treating fungible TokenApprove
amounts above 10^15 as unlimited, consistent with the existing EVM
threshold.

useMultichainTransactionDisplay now exposes
isUnlimitedApproval, sets approve titles to
transactions.tx_review_approve plus the token unit when available,
and only flags unlimited for TokenApprove (not send/receive).

MultichainTransactionListItem and
MultichainTransactionDetailsSheet use that flag to render
confirm.unlimited plus the token symbol instead of the raw numeric
string; bounded approvals still show the formatted amount (including
when to is empty but from has the movement).

Adds unit tests for the hook and UI; bumps
@metamask/tron-wallet-snap to 1.27.0.
