zeekay 02e5254ca8 refactor(dex): decomplect the synthetic-seed/guard footgun (3 layers -> 0)
The mess was three layers defending a self-inflicted footgun:
 (a) cmd/clobverify + cmd/fourpath-live SEED ascii-of-symbol synthetic
     markets (poolID = ASCII of "LUX/LUSD"), orders with no orderuser row;
 (b) internal/localguard refused those tools off-loopback;
 (c) VM.assertOrderUserCoverage BRICKED the chain at boot if a custody
     market had a resting order with no orderuser row.

Decomplect-perfect (NOT another guard):
 1. DELETE cmd/clobverify + cmd/fourpath-live. Real markets come from
    permissionless OpenMarket + real ERC-20s + the maker; the real-market
    e2e supersedes them. cmd/dexseed (canonical, structurally synthetic-safe)
    stays.
 2. DELETE internal/localguard (+ test) — it existed ONLY to fence the
    deleted seeders.
 3. The settlement-identity invariant already holds BY CONSTRUCTION at order
    creation: lockOrderSpend writes orderuser: and putOrderRow writes order:
    to the SAME versiondb overlay, committed in ONE atomic Block.Accept
    overlay.Commit(); an unfunded place never rests. So a resting custody
    order without its orderuser row is UNREPRESENTABLE in committed state ->
    the boot scan was provably dead -> DELETE VM.assertOrderUserCoverage.
    The single remaining settlement-identity guard is the consensus-time
    fail-closed in settleOrderEffects (ErrMissingSettlementUser), which can
    never fire on honest committed state.

TDD:
 - TestCommittedStateNeverHasOrderWithoutIdentity: drives the real commit
   path (rest + reject + fill); committed order: set == orderuser: set.
 - TestRestartDoesNotBrickBoot: hand-corrupts state the commit path cannot
   produce; boot now SUCCEEDS (no brick); consensus-time guard still fails
   closed when a fill touches the corrupt order.
 - All prior settlement-identity regression tests still pass.

Result: zero guards, illegal state unrepresentable. Removes the footgun
instead of guarding the footgun we created.
