Use the shared deposit-expiry helper when building autoloop DP
candidates so unconfirmed deposits do not look like the
earliest-expiring options.
This keeps the no-change selector's expiry tie-break aligned with the
generic loop-in deposit selection rules.
Replace the recursive full-deposit autoloop selector with a bounded-memory
DP implementation in staticaddr/loopin/autoloop_dp.go. The new selector
keeps the existing no-change semantics, first finds the best reachable
total, then applies the 25 percent band rule so earlier-expiring deposits
can win inside that near-optimal range.
The DP table is capped at 128 MiB and keeps exact satoshi sums alongside
compressed bucket weights, so planning stays memory-bounded without
allowing oversized candidates. The compressed weighting now rounds down
with a minimum of one bucket, which avoids rejecting valid sums after
multiple per-deposit rounding steps while leaving the exact-sum check
as the real safety boundary.
