Trustworthy sign_psbt amount/fee display for non-default sighash: integration tests

This commit only adds and updates automated integration tests for the Ledger Bitcoin app. It does not change the app's actual signing code. The tests verify that the device now shows clearer, more trustworthy on-screen amount and fee infor…

Trustworthy sign_psbt amount/fee display for non-default sighash: implementation

This commit changes how the Ledger Bitcoin app shows transaction amounts and fees on the device screen when a user signs a transaction that does not use the normal 'sign everything' rule (a so-called non-default sighash). Previously the ap…

Properly exclude SWAP-related code if ENABLE_SWAP != 1

This commit is a build-system cleanup for Ledger's Bitcoin app. It wraps all code related to the optional 'SWAP' feature inside #ifdef HAVE_SWAP guards so that, when the app is compiled without SWAP support, none of that code is compiled o…

Fixing LEDGER_ASSERT failures with strings exceeding internal MESSAGE_SIZE hard-coded to 50

This commit shortens a number of internal error messages in Ledger's Bitcoin app so they no longer exceed a 50-character internal limit. The title says the long messages were causing LEDGER_ASSERT failures, which means the app could crash …

Assertion message length exceeds internal buffer and triggers LEDGER_ASSERT failureNo change to cryptographic or signing logic; only diagnostic strings rewordedPotential for app crash/denial-of-service if long assertion messages are hit at runtime

Reducing buffer_ext module with most of the API now in the SDK
