fix: correct swapped min_pool_cost / coins_per_utxo_size

The paramProposalEncoder supplied paramProposalCoinsPerUtxoSize at
the slot reserved for min_pool_cost and paramProposalMinPoolCost at
the slot reserved for coins_per_utxo_size, so every row inserted
into param_proposal had the two column values swapped.

Swap the two lines in paramProposalEncoder so the encoder order
matches the ParamProposal record definition and paramProposalDecoder.

Existing rows written by affected versions remain swapped on disk
and need a resync (or one-off column-swap migration) to correct.

The ledger no longer provides them, so we historically delete them
for consistency

Useful after upgrades, where order may change

Nix: Fix wrong git revision in version

Fix exe permissions in release distribution

The binaries in the release archives (cardano-db-sync, cardano-smash-server,
and so on) are missing the executable permission. This is the unintended
consequence of respecting the default umask (introduced in #2023).

fix(docker): change node healthcheck from EKG to Prometheus

The blockio package defaults to io_uring which requires liburing.
The devx CI environment does not provide liburing, so we use the
serialblockio flag instead.

TODO: revert when CI provides liburing or switch to io_uring for
better LSM I/O performance.
