feat(explorer): Gated Send Tx for Foreclosed Applications

[brunomenezes]

Summary

This PR implements a safeguard that prevents users from accidentally trying to send transactions to foreclosed applications. It blocks and avoids the experience of getting a revert upon sending the transaction and provides clear, contextual feedback on why the action is restricted.

User Experience (UX) & Accessibility Changes

• The "Send" Button: Automatically disables if the application is "Foreclosed."
• Contextual Tooltip: Clicking the disabled button triggers a styled, multiline tooltip reading: “The application is foreclosed. You can no longer send transactions.”
• Accessibility (a11y): Added aria-disabled attributes to ensure screen readers properly communicate the button's locked state.

Risk & Verification

• Edge Cases Handled: Standard flows (wallet connection checks, network switching modals) still operate for active apps.
• Automated Coverage: Added 8 test cases covering all transaction types (Ether, ERC-20, ERC-721, ERC-1155) to guarantee no regressions in the core send-tx workflow.
