fix: reset usdt allowance

[AGMASO]

General Changes

• Fixes a bug in Umbrella staking for USDT where the requiresApprovalReset handling was missing. As a result, users were unable to stake, due to USDT's special case of requiring the allowance to be reset to zero before approving a higher amount.
• Fixes an edge case with USDT where an existing allowance below 1 unit was rounded down to 0, so requiresApprovalReset never fired and the approval reverted on-chain.

⚠️ Global Bundle Size Increased

Page	Size (compressed)
global	1.33 MB (🟡 +19 B)

Details

The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis
