Pull request description:

  Follow-up to #11413 providing a base to build on for #19543:

  - bugfix for `bumpfee` raising a JSON error with explicit feerates, fixes issue #20219
  - adds explicit feerate test coverage for `bumpfee`, `fundrawtransaction`, `walletcreatefundedpsbt`, `send`, `sendtoaddress`, and `sendmany`
  - improves a few related RPC error messages and `ParseConfirmTarget()` / error message
  - fixes/improves the explicit fee rate information in the 6 RPC helps, of which 2 were also missing `conf_target` sat/B units

  This provides a spec and regression coverage for the potential next step of a universal `sat/vB` feerate argument (see #19543), as well as immediate coverage and minimum fixes for 0.21.
