feat: Linux accessibility contract and Web persistence for Mortsom - #408
Conversation
On wasm32 the storage backend implemented only chat messages and the settings store, so a Web client never listed the orders it created or took and could not sign for them again after a reload. Add the trades and trade_keys object stores (schema version 2), store each trade as one JSON document keyed by its id, and patch documents field by field with the same semantics the SQLite backend gets from json_set. Orders, relays, identity and the outbox stay stubbed for the rest of #233.

Bootstrap skipped init_db on the web because there is no app data directory there, which left db() unset for the whole session: nothing the Rust core persisted on the web ever reached IndexedDB, so a Web client never listed the trades it created or took. init_db takes a database name on wasm, so open it with a fixed name and keep the file path off the web.

…ty and outbox With init_db now opening the store on the web, derive_trade_key requires identity persistence to succeed before handing out a key, so the identity stub made every order creation fail. Implement the remaining stores as JSON documents keyed like their SQLite rows (schema version 3); nothing in the backend is stubbed any more.

… mapping Review findings on #408. A trade patch read the document in one transaction and wrote it back in another, so two patches landing on the same trade within moments (status sync, peer reveal, reputation, rating) could each write a full copy and the later one drop the other's field. Read, patch and write now share one read-write transaction, as do the delete-by-order-id and the outbox status change. The living contract and task list now say what the code does: HoldInvoicePaymentSettled and Released mean payout pending, PurchaseCompleted means Success, and both parties rate only at Success.

… across awaits The single-transaction patch of the previous commit failed on the web: an IndexedDB transaction is active only while its own request callbacks run, and the Rust future continuing after an await is polled from a later task, so the write hit an inactive transaction and the seller's pay screen never got its hold invoice. Serialise every read-modify-write on a document with an async lock instead, which closes the lost-update window for this process, the database's only writer.

The daemon tells only the buyer about PurchaseCompleted; the seller learns of the payout solely from the public kind-38383 success event. A seller client that missed that one event stayed on payout pending forever, restarts included, because the stale sweep ignored SettledHoldInvoice. Confirm the payout against the book for up to a minute after the escrow settles, and let the sweep complete such trades on every pass.

…payout write Review findings on #408. A mutex inside one Rust instance cannot stop a second tab from overwriting a patched trade document, so whole-document writes, patches and deletes now also take an origin-wide Web Locks lock per store, falling back to the in-process mutex where the API is missing. The payout completion re-checks the local status under the per-order lock right before writing Success, so a dispute or cancel that landed during the book fetch is not overwritten. The public-status fetch checks the event author itself instead of trusting the relay's filter. The task list's independent test now describes rating at Success.
