* tpu-client: Move `send_messages_with_spinner` from program (#20960)
We have too many ways of sending transactions, and too many
reimplementations of the same logic all over the place.
The program deploy logic and stake-o-matic currently make the
most use of the TPU client, so this merges their implementations into
one place to be reused by both. Yay for consolidation!
(cherry picked from commit 5f7b60576f)
# Conflicts:
# cli/src/program.rs
# client/src/mock_sender.rs
* Fix merge issues, use older APIs
* Update mock sender fee to match block height
