Username and Password Validation rule are missing

[CodyHuynh-QA]

Description:
Validation rules for Username and Password fields are missing or improperly enforced. Current behavior allows invalid inputs such as single underscores, whitespace-only passwords, and entries without clear length or composition requirements.

Expected Result

Username

• Enforce minimum and maximum length (e.g., min 3, max 32).
• Automatically trim whitespace at both ends before validation.
• Reject usernames consisting only of underscores or whitespace.

Password

• Enforce minimum and maximum length (e.g., min 8, max 64).
• Reject passwords consisting only of whitespace.
• Require at least one letter, one number, and one special character.
• Provide clear error messages when requirements are not met.

Actual Result

Username

• Accepts single underscore _ and single-character inputs.
• No clear length restrictions.
• Does not trim whitespace automatically.

Password

• Accepts whitespace-only values.
• Accepts single-character inputs.
• No clear length restrictions.
• No requirement for letters, numbers, or special characters.
