[ING-422] Stop auto top-up failing when the refill exceeds the max limit

[aquinofb]

Context

When a wallet's automatic top-up needs to refill more than the wallet's maximum paid top-up amount, the refill was computed by the recurring rule and then rejected by the transaction creation step. Nothing was created and nothing was surfaced: no transaction, no invoice, no webhook. Auto top-up silently stopped, the wallet kept running dry, and the refill was retried and failed on every balance refresh.

The two rules contradicted each other: the recurring rule intentionally lets a target refill go past the max, because reaching the target balance matters most, but transaction creation re-checked the max and rejected the amount.

Changes

• Threshold and interval refills now create the transaction with the limit check disabled. The recurring rule already computed the amount (it applies the minimum, and for target rules deliberately reaches past the maximum), so re-checking the limits there could only reject a refill that was meant to happen.
• The interval flow now also honors the rule's ignore-limits setting, which it previously dropped.
• A fixed rule configured with a paid amount outside the wallet limits is now rejected when the wallet is created, the same way the update path already rejects it, so the misconfiguration surfaces immediately instead of failing on every trigger.
