Added detailed documentation to ECgFp5 point and scalar field code, clarifying group law, canonical encoding, and security properties. Enforced canonical input checks in scalar multiplication and Montgomery multiplication, with panics on invalid input. Updated tests to verify rejection of non-canonical scalars and correct handling of canonical cases. Improved Schnorr signature documentation, emphasizing prime order, canonical encoding, and the absence of cofactor-related attacks.
