Summary by Sourcery

Add support for a cloud-controlled force-update mode and integrate it into the web UI updater flow and scheduling.

New Features:

• Expose a cloud force-update control endpoint and helper to read its state from the deployment config.
• Add force-update handling in the web UI updater, allowing detected updates to run immediately when the force flag is enabled.
• Introduce a coroutine-based update check loop that adapts its polling interval based on whether force-update is enabled.

Enhancements:

• Extend the updater to track force-update state separately and to re-check the force flag when an update is already pending.
• Adjust application startup to schedule the new adaptive update-check loop instead of the previous fixed-interval check function.

Tests:

• Add unit tests covering updater behaviour for force-update on detection, deferred updates when force is disabled, enabling force-update after an update is already pending, and the force-update polling schedule.
