timer: Add ringing and counter

[vkareh]

The timer app currently issues a short buzz once and then disappears. There is no trace left that the timer finished or how long ago. This change makes the motor start ringing and presents a timer counter. The motor will continue the ringing pattern for 10 seconds and the timer counter will finally reset after 60 seconds.

Works great, huge usability improvement for the timer. Been running this for a while and it makes me a more consistent cook for sure!

I think it would be nice if the alarm and timer had different vibration patterns, but vibration needs to be overhauled anyway so this is good to go for now IMO

[mark9064]

I see why you changed this (count up after ringing), but we probably want to avoid relying on UB

Tested this today while cooking and this is indeed a great usability improvement for the timer.

Until now i missed a lot of the alarms, the vibration is just too short. Great work.

@vkareh I fixed the infinite buzzing issue I raised above in a PR on your fork here. It just creates a wake lock while the exipred timer is less than 11 seconds and the motorController is buzzing, and releases it after.

It's a bit hidden so just in case I responded to the timer method semantics problem here: https://github.com/InfiniTimeOrg/InfiniTime/pull/1971/files#r2492311746

Would be super great to get this in for 1.16 which we're hoping to release in the next few days :)

I've just tested this PR and it looks very good, thanks @vkareh !
One thing I noticed : when the timer reaches 00:00, it looks like it stays on that value for 2 seconds before showing 00:01. It's not a big deal, but I think it makes the "elapsed for xx seconds" value off by one second.

I think this is the correct behaviour since the time always rounds to zero.

actual | shown
 5.00 | 5
 4.99 | 4
 4.00 | 4
...
 1.00 | 1
 0.99 | 0
 0.00 | 0
-0.99 | 0
-1.00 | 1
-1.99 | 1
-2.00 | 2

so you should expect it to show 0 for 2 seconds (from time +1 to -1)

@mark9064 Good point, that makes sense! 👍

[mark9064]

@vkareh #2365 is in :) let me know if it all works ok when you get around to rebasing on to it

[DavisNT]

Could it be possible to add an option to ring indefinitely (in many cases people will not notice the 10 seconds ringing, especially if the timer is used during physical activity/sports)?

[mark9064]

I totally get where you're coming from but I think it'd be best to choose one sensible default here. At least how I've been using the timer 10s ringing has felt good to me, even if I'm moving about I definitely notice it before it stops. I'm not sure if you've had the chance to try this PR yet, but if not maybe give it a go and see how you find 10s? Maybe it's more noticeable than you'd think :)
