Statistics UI refinement

We have a much better Statistics page now, as before.

Here are some ideas for a further refinement:

Motivation
The columns Bolus, Basal and Basal% make no sense with SMB, and limited sense with AMA.
While seeing TDD, Carbs and TIR values in the same line provide an informative overview, if profile change/tuning is needed.

Changes (v2)

• Delete columns: Bolus, Basal, Basal%
• Rename column Sum to TDD
• Move column carbs to the left
• Move TIR(3,9-10,0) to the right beside TDD and Carbs
• Move title TIR(3,9-10,0) above 3 right columns
• Delete titles: average, today, TDD, etc.
• Rename Title Average (3,9-7,8) to TIR (3,9-7,8)
• Move 30 days under 07 days
• Separate card for today on top
• Separate card for TIR (3,9-7,8) on the bottom
  update 2023-02-07 (not in the picture):
• an additional column with the mean SGV would indicate sensitivity changes
• if today is on top, the last 7 days should decrease (newest on top)

Notice the space freed up with dumping Bolus, Basal, Basal% and uniting the spreadsheets, too.

Changes (v3)

• Move units to column titles - to let the eye focus on the values

Optional

• Coloring of values of individual days:
  red = high TDD, Carb, Below and Above and low TIR
  white = for near average values
  green = for the rest

If Bolus, Basal, Basal% seems to be very important, I'd suggest to leave only Basal%, and this could even fit in an own column in the 3rd image.

No files or tests are named. Start by locating the Android Statistics page implementation and compare it with the screenshots and requested v2/v3 changes; done means the columns, ordering, titles, cards, units, and optional SGV presentation match an agreed design without disrupting existing statistics behavior.
