feat: hardware wallets settings

[ovitrif]

Closes #1026
Refs #998

This PR adds a Hardware Wallets settings screen for viewing and managing paired devices, reachable from Settings under General › Payments.

Description

• Adds a "Hardware Wallets" row to Settings ▸ General ▸ Payments whose value shows the paired-device count and opens the new screen.
• Adds the Hardware Wallets settings screen: a list of paired devices (connection badge that turns green when connected, device name, balance) each with a per-row delete, plus an "Add Hardware Wallet" button that opens the existing Connect Hardware flow.
• Removing a device reuses the existing confirm dialog ("your funds are safe…"); the view-model's removal state is now scoped to the tapped device so per-row delete targets the right one.
• Extracts the shared HW wallet UI components.

Figma Designs:

• Settings General
• Hardware Wallets

QA Notes

Manual Tests

• 1. Settings → General → Payments: "Hardware Wallets" row shows with the paired-device count.
• 2. Settings → tap Hardware Wallets: each paired device is listed with a connection badge, name and ₿ balance; a connected device shows a green badge.
• 3a. Hardware Wallets → tap a device's trash icon: confirm dialog appears explaining funds are safe.
  • 3b. tap Cancel: the device stays listed.
  • 3c. tap trash again → Remove: the device is removed and the Settings "Hardware Wallets" count decrements.
• 4. Hardware Wallets → tap Add Hardware Wallet: the Connect Hardware intro sheet opens.
• 5. No paired devices → Hardware Wallets: empty state and the Add Hardware Wallet button are shown.

Automated Checks

• Unit tests updated: device-scoped removal dialog in HwWalletViewModelTest.kt (stores the tapped device, clears it on dismiss/remove, and delegates removal with the right id).
• Journey added: settings-hardware-wallets.xml drives the count row, device list, Add sheet and per-row delete against the Trezor emulator.
• CI: standard compile, unit test, and detekt checks run by the PR bot.
