fix: make order search case-insensitive

instr() in SQLite compares bytes, so searching for a customer name
in uppercase (e.g. "JOHN") silently missed lowercase-stored matches
like "John". Lowercase both sides of the order number, name, and
email comparisons so search matches regardless of the case staff
paste in.
