fix: proper CI prebuilt for linux

* new trezor connection ui

* fix page title

* typo

* fix page title anim

* refactor: enhance Trezor pairing flow, update state management, and simplify UI logic in hardware wallet integration

* fix: correct widget indentation in Trezor pairing failure state UI

* fix: extract Trezor pairing failure state UI to `_errorBox` widget and update Trezor dependency reference

* feat: add USB intent filters, device filter for hardware wallets, and update Trezor dependency reference

* Update cw_monero/pubspec.yaml [skip ci]

* Update cw_wownero/pubspec.yaml [skip ci]

* Update cw_zano/pubspec.yaml [skip ci]

* fix: use CryptoCurrency.title instead of amount-refactor-only .symbol getter

new_wallet_type_page used curr.symbol, which only exists on the
amount-refactor branch (String get symbol => title). On dev the
equivalent is curr.title. Adapts the Trezor feature to dev's API
without pulling in amount-refactor.

The short version

What changed, and why it matters

This is a large feature commit that adds Trezor hardware wallet support for Monero to the Cake Wallet app, alongside Ledger and BitBox. It also refreshes the hardware wallet connection UI, updates dependencies, and bumps the Android minimum SDK. The changes are mostly new feature code rather than a fix for a known security flaw. There are no explicit security claims in the commit message or diff, and no independent vulnerability disclosure is referenced.

Recommended action

Review the Trezor signing and key-image sync implementation for correct validation of device responses, ensure the new dependency versions do not introduce known regressions, and verify that the USB/BLE permission and intent-filter changes do not expose unintended attack surface. Treat this as a normal feature/security review rather than an urgent patch.

Security signals we found

01

New hardware wallet signing path added for Monero via Trezor

02

Dependency updates for cryptographic/Bluetooth/USB libraries

03

Android USB intent filters and device filters added for hardware wallets

04

Refactored hardware wallet connection state checks across send, swap, buy, and dEuro flows

05

New Trezor pairing UI with PIN entry and state management
