use native BigInt instead of the big-integer library

mariuz

committed

Explicitly convert A, B, and private keys (a/b) to BigInt at the entry points (clientProof and serverSession

committed

Restore robustness (preventing the crash), we need to explicitly handle number inputs in toBigInt.

Fix serverSession: Updated to calculate x (user hash) and apply the (u * x) % PRIME.N reduction, ensuring it matches the logic in clientSession and the Firebird engine.

use fixed Server key for tests

Modify serverSession to accept an optional a parameter. If provided, it calculates the session secret using the reduced exponent logic

compare it to cpp implementation

serverSession must be updated to match the client's behavior by explicitly calculating x and applying the modulo reduction to the exponent

modify toBigInt to only treat strings as floating-point numbers if they contain a decimal point . or if they are NOT valid hexadecimal strings.

While a (private key) is typically small (32 bytes) compared to N (128 bytes), making overflow unlikely, applying the modulo ensures consistency with the Firebird implementation and other clients.
