02b5f6078d fees: make flushes log debug only (ismaelsadeeq)
Pull request description:
This is a simple PR that updates the flushing log to use debug-level logging under the estimatefee category. It also ensures the log consistently includes only the full file path.
The motivation behind this is that the "Flushed fee estimates to fee_estimates.dat." logs can become noisy; it's done after one hour, so hiding it in the debug estimatefee category seems reasonable.
---
I left the logs when the file is not found as info because that should only occur when you start a fresh node, change datadir, or explicitly delete the file
