feat: monitor sealevel ATA payer balances in the key funder

[tkporter]

Description

• Tested and set up alerts
• We already have the relayer balances from the agents themselves, so just need the ATA payers (which are responsible for paying for the rent of token accounts that don't yet exist when bridging in)
• Putting it here because it's easy and this is what we did in v2 (see Hacky solana balance monitoring #3432, which this is based off)
