android: add Live Update notification and popup toggles

[thisisAcidic]

Adds three options in Settings under a new "Popup Animations" section:

1. Toggle to disable the bottom-sheet popup that appears on every connection.
2. Toggle to disable the Dynamic Island style popup at the top of the screen.
3. A Live Update notification (Notification.ProgressStyle, setRequestPromotedOngoing) with persistent battery, heads-up on connect/takeover/listening-mode/low-battery, and a case-open reminder when case battery is below 30%.

The Live Update notification declares the Samsung Now Bar opt-in metadata for One UI 7+ and uses CATEGORY_STATUS plus ongoingActivityNoti.style extras. Android 16 surfaces it as a Live Update on systems that adopt the API (ColorOS 16, One UI 8). On systems with a hardcoded whitelist (ColorOS 15, One UI 7) the same notification appears as a regular HIGH-importance heads-up plus an ongoing entry in the shade.

First Live Update fires from the BLE-advertised battery so it shows up immediately on connect rather than waiting for the L2CAP socket handshake.

Migration: existing installs (connection_successful pref already true) default the new Live Update toggle to OFF, keeping the legacy LOW-priority shade notification. Fresh installs default to ON.

Tested on Oppo with ColorOS 16. Build clean.

Thanks for the PR!

Could you please share a screenshot of how this looks on Oppo?

Sure, here are two from my Oppo Find X9 Pro. On connection the live notif goes into heads-up state, meaning it shows the live notif in full for 2 seconds (First pic), then it automatically goes into the normal background pill only showing the lowest percentage (second pic). Heads up will trigger on events and low battery.
