bug: Prover node does not wait until the last block in the epoch for sending a quote

[spalladino]

Extract from the e2e_epochs test from #10045:

aztec:prover-node 48.557s [INFO] Sending quote for epoch 1 with blocks 3 to 5 epochToProve=1 validUntilSlot=9007199254740991 bondAmount=1000 prover=0x3c44cdddb6a900fa2b585dd299e03d12fa4293bc basisPointFee=100 +9s
aztec:sequencer 51.094s [INFO] Submitted rollup block 6 with 0 transactions duration=78ms (Submitter: 0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266) +3s
aztec:e2e_epochs 51.162s [INFO] L1 block 16 mined at 1732138969 with new L2 block 6 for epoch 1 +3s

Note that prover node is sending the quote as soon as block 5 is mined, but the last block in the epoch is actually 6.
