Subject: [PATCH] fix: make username (account_id) lookups case-insensitive

Normalize account_id and product_id to lowercase before DynamoDB queries
so that URLs like /ALukach resolve correctly to the /alukach account.
Also redirect mixed-case account page URLs to their canonical lowercase form.

Closes #299
