Tolk verification fails: TypeError: 8440158398488578882 is out of safe integer range

Description

Attempting to verify a Tolk 1.2.0 contract on verifier.ton.org fails with:

Error: Server error TypeError: 8440158398488578882 is out of safe integer range

Steps to reproduce

1. Go to https://verifier.ton.org
2. Enter contract address: EQCYFR0gg9vN1zYV_4v3XRuC2SfZg5HRhcs64ccLUAUlftjp
3. Select compiler: Tolk 1.2.0
4. Upload Tolk source files (minter contract with imports: constants, errors, fees-management, jetton-utils, messages, storage)
5. Click verify

Expected behavior

Verification should succeed (or fail with a compilation mismatch error).

Actual behavior

Server returns TypeError: 8440158398488578882 is out of safe integer range

The number 8440158398488578882 exceeds Number.MAX_SAFE_INTEGER (9007199254740991). The backend likely needs to use BigInt when parsing this value.

Environment

• Compiler: Tolk 1.2.0
• Contract: TEP-74 Jetton Minter with custom getters
• Tried both "verifier.ton.org" and "orbs.com" backends — same error
• Browser: Chrome (latest)
