[Eco Bounty]QS Allows Purchase with Invalid/Empty Name (e.g., " . ") – Poor Input Validation

Summary:
The billing/purchase flow permits transactions with clearly invalid names such as " . " (dot or space-dot), bypassing basic input validation. This could lead to issues with order processing, emails, or account linking.

Steps to Reproduce:

1. Navigate to purchase flow (e.g., Quicksilver credits or subscription).

2. Enter an invalid name like " . " (single space-dot or dot only) in the name field.

3. Complete the purchase process.

4. Observe: Purchase goes through successfully (email confirmation sent, etc.), despite invalid input.

Expected Behavior:

• Reject invalid names (e.g., too short, only punctuation/spaces).

• Prompt user for a valid name (e.g., minimum 12 characters, letters only).

• Prevent submission until fixed.

Actual Behavior:

• Invalid name like " . " is accepted.

• Purchase processes normally (e.g., credits may/may not reflect, but order confirms).
