Send form input validation for amount and destination

[phertyameen]

Location

frontend/app/send/

Problem

The send form likely accepts amount and destination without client-side validation against Stellar address format and minimum/maximum transfer amounts, risking failed on-chain transactions after the user has already committed.

Acceptance Criteria

• Invalid Stellar destination format rejected before submission
• Amount below minimum or above sender balance blocked client-side with a clear message
• Validation errors shown inline, not just on submit
