LCW-1128-Add-support-for-Trezor (#2565)

* feat: add support for Trezor hardware wallet integration Restore Wallets * feat: add Trezor hardware wallet support, implement RLP decoding utility, and update transaction signing logic * feat: add bitcoin trezor signing * chore: update Trezor Connect dependency to specific commit hash in pubspec_base.yaml * feat: add trezor support for litecoin * feat: add colorFilter for device manufacturer icons to align with theme styles * refactor: optimize Trezor callback handling * feat: add BitBox and Trezor support for Bitcoin and Litecoin, update transaction signing logic, and improve modularity in hardware wallet services * refactor: simplify constructor assertions in `BaseBottomSheetWidget` and cleanup Trezor chainId handling logic * feat: conditionally render device manufacturers based on platform and hide SeedSigner for now
