[client] expose LazyConnectionEnabled in Android Preferences bridge

[MichaelUray]

Describe your changes

Adds two methods to the Android Preferences bridge so the Android UI can read and write the existing LazyConnectionEnabled engine setting:

• GetLazyConnectionEnabled() (bool, error)
• SetLazyConnectionEnabled(enabled bool)

The implementation mirrors the adjacent BlockInbound bridge: it returns the in-memory configInput value first if set, otherwise falls back to reading the persisted config; the setter buffers the value in configInput and waits for Commit().

Issue ticket number and link

N/A — bridge addition only, no behavior change in the engine.

Checklist

• Is it a bug fix
• Is a typo/documentation fix

• It is a refactor

Documentation

Select exactly one:

• I added/updated documentation for this change
• Documentation is not needed for this change (explain why)

This is an internal Go-mobile bridge addition with no user-facing surface in this repo. The LazyConnectionEnabled setting itself is already honored by the engine and presumably already documented at the engine level. The Android UI that consumes these methods is filed at netbirdio/android-client#171; if user docs are needed for the toggle, they belong with that UI change.

Docs PR URL (required if "docs added" is checked)

N/A.

Notes

• The LazyConnectionEnabled field already exists in client/internal/profilemanager/config.go and is honored by the engine; this change only exposes it through the gomobile bridge.
• Companion UI work that consumes these methods is filed at Add Lazy connection toggle to Advanced settings android-client#171.
• Verified locally with go build ./client/android/... and go test ./client/android/... (existing tests pass; no new test added because the new methods are pure passthroughs to the well-tested configInput / ReadConfig / UpdateOrCreateConfig code paths). Tested end-to-end on a Galaxy S21 (Android 15) — toggle in the Android UI persists LazyConnectionEnabled to the config file and the engine activates the lazy-connection manager (setup lazy connection service, per-peer activity listeners on 127.0.0.1:N, 15-minute inactivity threshold) as expected.

📝 Walkthrough

Walkthrough

Two new accessor methods are added to the Android Preferences struct for managing a "lazy-connection" setting. The getter retrieves the cached value or loads from config, while the setter updates the in-memory field pending the existing commit operation.

Lazy hops through Android lands so fair, 🐰
A preference blooms with gentle care,
Get and set with patterns tried and true,
Connection settings fresh and new! ✨
