Simplify: one Lightning path, one balance, fewer features

Dropped: silent payments (feature, wallet chains, scan worker, indexer
config), Boltz submarine/reverse swaps (feature + swap.js + tools), the
third-party ark swap bridge (config, client flows, settings card — the
ASP's own Lightning send is the one path now), and the Consolidate
coins settings action.

The NWC pouch is gone with them: background answering now spends the
WHOLE ark balance. The IndexedDB record mirrors the real manager state
plus the chain-3 keys for its live coins and a change-index window; the
worker pays through the ASP exactly like the open app, and the app
folds the worker's spends, change, and key allocations back in on
connect (additive merge + reconcile against the server). A leftover
chain-6 pouch from the short-lived pouch era is swept home
automatically using the keys stored in its own record. The stated
tradeoff: same-origin script access now reaches the ark balance, not a
carve-out — the ark balance is walking-around money, the on-chain
wallet's keys are never mirrored, and per-connection NWC budgets remain
the enforced ceiling.

Bundle: 726KB -> 602KB.
