Drop unused Data.ByteString.Lazy / Data.List / Data.IntMap imports 
Upstream cleanup, not Leios-specific: eight unused-import warnings that
upstream's own ghc-options promote to errors via 'nix/ouroboros-network.nix'
('-Werror' on forAllProjectPackages). They've been present at the
'main-peras-5202-merged' SHA that cardano-node and ouroboros-consensus
master both consume; surface when downstream haskell.nix builds also
inherit `-Werror`.

Affected files (one unused qualified import each):
- framework/lib/Ouroboros/Network/Protocol/Handshake/Codec.hs (BL)
- framework/tests-lib/.../ConnectionManager/Experiments.hs (LBS)
- framework/io-tests/.../Driver.hs (List)
- framework/io-tests/.../Socket.hs (IntMap)
- tests/lib/.../TxSubmission/AppV1.hs (BSL)
- tests/lib/.../TxSubmission/AppV2.hs (BSL)
- protocols/tests-lib/.../KeepAlive/Test.hs (BL)
- protocols/tests-lib/.../PeerSharing/Test.hs (BL)

Verified with 'cabal clean && cabal build all --ghc-options=-Werror' →
exit 0.

Leios N: add field names to Reception 
Replace the positional definition of `Reception` with named fields
`receivalTimes` and `received`:

    data Reception a = MkReception
      { receivalTimes :: !(IntMap Time)
      , received      :: !a
      }

Positional pattern matches continue to work; the fields just make
record-style access available where it reads better.

Leios N: Reception arrival-time on recv (demo-tuning) 
Wrap `Channel m a` recv values in a new `Reception a = MkReception
!(IntMap Time) !a`, recording per-chunk arrival times.  In the mux
demuxer the chunk's arrival time is paired with its starting byte
offset; codec/driver layers either strip the time map (the codec sees
only bytes) or propagate it through `wrapMiniProtocolTrailing` at the
mini-protocol callback boundary.  Tests/demos/benches use `IntMap.empty`
when synthesising trailing.

This is the network half of the November Leios demo's arrival-time
plumbing; consumers (e.g. Praos block-arrival tracing on the consensus
side) will be wired up separately.
