fix(card-deposit): remove gasless minimum deposit requirement

[MusabShakeel576]

Summary

Cherry-pick of #2042 from qa to master.

• Removes the gasless minimum deposit gate in the deposit-to-card modal so any amount can be deposited gaslessly.
• Updates useDepositFromSolidUsdc to skip the minimum-amount throw for DepositCategory.CARD (savings deposits keep their existing minimum).
• Simplifies the gasless badge UI — no more red warning state below MINIMUM_SPONSOR_AMOUNT.

Test plan

• Open the deposit-to-card modal in production, confirm gasless badge shows the neutral "Gasless deposit" copy at any non-zero amount.
• Submit a card deposit below EXPO_PUBLIC_MINIMUM_SPONSOR_AMOUNT and confirm the transaction is no longer rejected client-side.
• Confirm a savings deposit below the minimum still surfaces the original error (unchanged behavior).
