Description
Implement an emergency exit mechanism for owner to withdraw all funds if contract is paused.

I'm an experienced Open Source project contributor and I'm graduated from Web3Bridge and Starknet Bootcamp with honors. I've also worked on some projects implementing that functionality. So, I already know how it's works.

I am a protocol engineer with around 2+ years of experience writing, testing and deploying smart contracts in solidity, rust and cairo. I have worked for protocols like whrrl, hashstack, troves ( prev Strkfarm ) and endur. Tasks such as this come right under my belt. Would love to take this issue

Hi! I've already worked with Soroban smart contracts and some Starknet/Cairo codebases. Short plan:

• Add an EmergencyWithdrawal event and an emergency_withdraw(token, to) hook in StarkRemit, make it only callable by the protocol owner, reuse the token contract’s paused flag, and move the whole ERC20 balance with the same dispatcher pattern
  as other transfers.
• Expose the new call through IStarkRemit so the dispatcher can invoke it.
• Expand the snforge test: seed STRK into StarkRemit, pause the token, check the owner path succeeds, and make sure non-owner or unpaused calls fail.
