Fixes #1768

This PR introduces a notification alert when the connected device's battery drops below 20%. It ensures users are notified once per connection session to prevent spamming while handling reconnections properly.

1/ can you drop a demo video ?
2/ why did we need the set has low level battery on device connected ? https://github.com/BasedHardware/omi/pull/1797/files#diff-c887ba3d8e70bca5b4d97dea1232849b8d79206eee68544d4752e9292c8f7224R273
3/ please re-format the code with line length 120

1.) Right now, I do not have a device with me to test it perfectly. I need help from the person having device to test it,
2.) It's for an edge case, Assume the device battery is less than 20% and you got connected to the app then you will receive an alert notification. And now you disconnected the device but not yet closed the app and its still on foreground/background running and if you connect now with the device it will alert you again.

That is why _hasLowBatteryAlerted is set to false when device is reconnected again and the app is in foreground/background

3.) Yup, will do it now. But i wanted to know if it worked well with the device

1/ could you find the people in our community yourself ? http://omi.discord.com . testing is a must.
2/ what do you think about, just reseting the state of _hasLowBatteryAlerted to false, then waiting for the change ? just in case the batteryLevel is belong the old device. and, should do we do on the device disconnected ?

1/ yeah will find out and update
2/ the initial state of the _hasLowBatteryAlerted is false which means if any device that is connected having battery lower than 20% will be notified. But in an edge case where the first device is notified for low battery then _hasLowBatteryAlerted is set to true and if it is disconnected and again if the device is connected while still keeping the app state in foreground then it wont notify if we dont set _hasLowBatteryAlerted to false (default value)

@mdmohsin7
Can you help me by testing out this ?

@mdmohsin7 Can you help me by testing out this ?

@joshijoe05 it works! Tested quite a few times (I guess around 8-10), and 2 times I got the notification twice

[mdmohsin7]

Pls set the line length to 120 in your code editor

[joshijoe05]

@mdmohsin7
Thank you man for testing it.
I have changed the line length to 120 !

1/ are you done ?
2/ ✅ ok. overall, the logic is not super solid btw lgtm. absolutely, you can simplify it - but later.
