[HACK][Woo POS] PR 4/5: Integrate card reader connection into WooPos screens

[kidinov]

WOOMOB-1854

Description

Wire up the card reader connection dialog into WooPos screens:

• Home screen shows connection dialog when reader is disconnected
• Settings screen gets card reader update action
• Toolbar and totals ViewModels trigger connection flow when needed
• Update related tests

Test Steps

• Verify connection and update flows work in the POS
• Smoke test IPP

• I have considered if this change warrants release notes and have added them to RELEASE-NOTES.txt if necessary. Use the "[Internal]" label for non-user-facing changes.
