chore(perpetuals): add token address to deposit and withdraw events

[MohammadNassar1]

Note

Introduces token_address in key events to make the emitting token explicit.

• Extend Deposit, DepositProcessed, DepositCanceled, Withdraw, and ForcedWithdraw events with token_address (in deposit/events.cairo, withdrawal_manager.cairo, and core/events.cairo)
• Update emit sites in deposit_manager.cairo and withdrawal_manager.cairo; _withdraw now returns (hash, token_address) for event emission
• Adjust tests and helpers to assert token_address across deposit/withdraw flows (event_test_utils.cairo, flow and unit tests)
