pub fn normalize_wdp_input(input: &str) -> StringExpand description
Normalize input for WDP hash computation
Per WDP Part 5, Section 3.3:
- Trim leading and trailing whitespace
- Convert to uppercase
This ensures case-insensitive lookups and typo resilience:
E.Auth.Token.001→E.AUTH.TOKEN.001e.auth.token.001→E.AUTH.TOKEN.001E.Auth.Token.001→E.AUTH.TOKEN.001
All produce the same hash.
