refactor: simplify submit publication (fixed stake, derived fee)

[SiegfriedBz]

Summary

Contract

• Simplify submitPublication by removing the _paidSubmissionFee parameter and deriving paidFee from msg.value - I_PUBLISHER_STAKE.
• Replace previous fee/stake validation with a single minimum-payment check: msg.value >= I_PUBLISHER_STAKE + I_PUBLISHER_MIN_FEE.
• Update all Foundry tests and helpers for the new function signature and revert behavior.

Front End

• Simplify the frontend submission UX by removing the user stake input entirely and turning the fee box into a read-only breakdown (fixed stake + estimated fee + total).
• Regenerate the TS contract config to sync the ABI change.

Deployments

• Base Sepolia
• Ethereum Sepolia
