Database size on status page

[Navid200]

This PR adds a new item to classic status page, the database size.
It removes the phrase "downgradable to" from the same status page.

I think this is very messy what you're doing here. You're trying to use asynchronous features synchronously and creating a lot of weight for something that really doesn't need to be that complicated. See the new utility method I have provided for this. I suggest completely reworking this PR to just use that: 53507c7

Thanks you so much.
Will be done.

[Navid200]

Thanks for the guidance.
It should be good now.
Thanks

@Navid200 What is the use-case that benefit of knowing database size?

[Navid200]

@olorinmaia If you have been using xDrip for years, the database may contain data you will never need inside xDrip any longer. Keeping data in xDrip corresponding to 20 years ago is not necessary.

I welcome suggestions as to what could be the cause of this: #1280
In the meantime, I would suggest to everyone to avoid allowing their database to unnecessarily grow.

Being able to see the size of the database can be useful for deciding when you may want to do some cleanup.

Thanks for some info regarding this. If database cleaning is necessary, is this the way or is there other methods?

I mean setting Glucose retention to e.g. 365.

Thanks for that link. I will need to update that.

Yes, setting glucose retention to a value like 365 is a way to limit the size.
