Refuse tiny amounts that convert to zero base units and require whole numbers for the Shamir threshold and share count.

Gateway amounts use an exact conversion that refuses more digits than the asset has, toBaseUnits keeps its rounding for existing callers, the connected-app column is only added for WalletConnect and Liquid, and small cleanups. Also restores LF line endings in files touched by the previous commit.

Only link a registry owner URL that points at the labelled repository, convert gateway amounts without binary noise, show the connected-app column only for WalletConnect and Liquid, and let the whole E2E config honour E2E_PORT.

Validate the merchant page fee like Pay and Sign, derive the gateway fee cap from the shared constant, keep config.json available offline through a network-first runtime cache, and stop resetting the hello guard before a pairing succeeds.

Keep a malformed fee as text when decimals are given, allow the asset's own fraction digits in the gateway builder, and do not show the asset error while the lookup is still running.

An online key registration transaction with voteFirst=0 (a legitimate
round value) failed to encode: the field was dropped during msgpack
serialization because OptionalSchema treats the wrapped schema's default
(0 for Uint64Schema) as an omit-empty default. On decode the field was
restored as undefined, so reconstructing the Transaction threw "Online
key registration missing at least one of the following fields: voteKey,
selectionKey, voteFirst, voteLast, voteKeyDilution". The same error
occurred when decoding a block containing such a transaction.

Introduce SparseOptionalSchema, which treats only `undefined` (not the
wrapped schema's zero default) as omittable, and use it for the votefst,
votelst and votekd fields. These fields remain omittable so they stay
absent on non-keyreg transactions, leaving other transaction types' wire
format unchanged.

Fixes #925

Ignore non-numeric amounts in Pay and Sign, update example links to microalgo fees, cap the gateway builder fee, bound the Shamir share count, and show the localized unknown label for requests without a known session.

Round fee amounts to whole microalgos, refuse gateway amounts that scale to zero base units, keep raw amount text in the protocol parser, drop a stored Liquid credential on binding mismatch, preserve watch-only data on replace, and add E2E specs for the gateway builder and Shamir threshold. Direct E2E specs honour E2E_PORT.

Under UseAccess, MakeApplicationCallTxWithAccess passed a ForeignAssets
entry of 0 straight into the access list, appending a zero-valued
(empty) ResourceRef. The AVM treats that as an empty box reference
rather than an asset reference, so a 0 asset id silently produced a
different, incorrect transaction instead of an error.

Reject asset id 0 in the access-list composition so callers must pass
an explicit box reference for that behavior.

Fixes #764.

Keep typed passwords after a failed change, require the network minimum
for a link fee, share the ARC-14 realm constants, reject self-payments of
the payee in the gateway, replace unknown with real types, cache the
request-table descriptions, and tidy the Liquid hello/credential checks.

Validate the stable-workflow tag and pass it through env, run the duplicate
account guard before any state change and let a signing account replace a
watch-only entry, reset Liquid hello per connection, keep link amounts as
text, bound the gateway amount, and keep the app rows on WC/Liquid.

Store the Liquid credential only after the wallet binding is checked,
refresh Liquid peer metadata per connection, require a transaction type
at admission, reject malformed gateway link amounts, exact base-unit
arithmetic and an error message in the gateway builder, a localized fee
toast, and a duplicate-account guard in every add-account mutation.
