91. Clean Phone Numbers with replace

replace(s, find, with) swaps every occurrence of a substring. Nesting replace calls lets you strip several unwanted characters in one expression.

Task: for each contact return id, the original phone, and clean — the phone number with spaces, dashes (-) and parentheses removed, leaving only digits. Apply replace four times (remove ' ', '-', '(', ')'). Order by id.

Output columns, in order: id, phone, clean.
