[ECO Bounty] Mimo Exchange Missing "Do Not Show Again" Option for Delisted Assets Warning Modal

Description

When selecting delisted assets like USDC, USDT, WETH, or WBTC for bridging:

• Warning modal displays: "Assets IOTX, USDC, USDT, WETH and WBTC have been delisted. Delisted assets have no security guarantee..."

• Options available: X (Close) or View Official Notice

• No "Do Not Show Again" option to suppress future warnings for informed users

Orange arrows in the screenshot highlight the Connect Wallet button and X close button, emphasizing repetitive dismissal frustration.

Steps to Reproduce

1. Open mimo.exchange in mobile browser

2. Navigate to Bridge section

3. Select a delisted asset (e.g., USDC, USDT, WETH, WBTC) for "You Pay" or "You Receive"

4. Attempt to proceed → Warning modal appears

5. Dismiss with X

6. Repeat steps 3-4 → Warning reappears every time

Expected Behavior

• Warning modal includes "☑️ Do Not Show Again" checkbox/toggle

• If checked and dismissed, warning is suppressed for future sessions (via localStorage or account preference)

• UX allows power users to bypass repetitive warnings after acknowledgment

Actual Behavior

• Warning reappears on every asset selection/bridge attempt

• Users forced to tap X repeatedly with no suppression option

• No persistence of user acknowledgment

Suggested Fix

1. Add "☑️ Do Not Show Again" checkbox at bottom of modal

2. On dismiss with checkbox → set localStorage: localStorage.setItem('delistedAssetsWarningDismissed', 'true')

3. Before modal trigger → check storage: if true, skip modal

4. Optional: Per-asset toggles or account-based persistence
