feat(wallet-metadata): Artemision opts into the ADR-0057 commitment on every MBA genesis

The wizard already classifies the user's intent via mint/supply/backing
axes (DEA / PLA / MCA / MTA) — now it also threads that `assetClass`
into the `GenesisIntent` so the planner can emit the 40-byte metadata
commitment on the minting NFT. Zero new UI copy; from this commit on,
every non-adjustable-fee MBA minted through Artemision carries a fully-
on-chain, offline-resolvable (ticker + decimals + class) record on its
minting-baton NFT.

- shells/app/src/screens/ArtemisionScreen.tsx:
  • Import classifyAssetClass from @core/token/assetClass
  • Compute mbaAssetClass = classifyAssetClass({backing:'mba', mint, supply})
    at plan time
  • Pass it to planGenesis as `assetClass`, mutually exclusive with
    `adjustableFee` (that path uses the commitment for live feeBps —
    the planner's own guard refuses the overlay; the UI mirrors it
    at the call site for clarity)

- wiki/decisions.md: ADR-0057 "UI opt-in path" section updated from
  "deferred" → "SHIPPED", and the NBA case called out as a follow-on
  because ADR-0054 (capped NBA cap-as-consensus) skips the minting NFT
  entirely for capped assets so the commitment has no carrier.

Regression:
- Full Vite build clean (shells/app)
- 47/47 core tests (test/unit/wallet/metadata-commitment + genesis)
- 31/31 shells/app BCMR-resolver tests
- tsc clean on shells/app

With steps 1 + 2 + 3 + UI opt-in all shipped, the metadata stack is
end-to-end for MBAs: Artemision wizard → planner emits NFT commitment +
BCMR OP_RETURN → BCMR uploaded to Sia via /api/bcmr-upload → consumer
in shells/app resolves it on first balance load → ticker/name shown.

-Artemision wizard needs a one-liner change later: pass the already-classified
-`assetClass` (which the create flow computes from mint/supply/backing axes
-anyway via `classifyAssetClass()`) into `prepareGenesis`. Zero new UI; purely
-plumbing in `ArtemisionScreen.tsx` when it builds the `GenesisIntent`. Left for

+`ArtemisionScreen.tsx` now computes `mbaAssetClass = classifyAssetClass({

+and threads it into the MBA `GenesisIntent`. Opt-in is mutually exclusive with
