This commit is part of the refactoring and improvement of the html and css of account_reports (enterprise).
Here we:
- Remove blank_if_zero default value of True, it is now False by default. The zeros are now shown in a muted gray color.
- As we had a level of hierarchy 0 that allows for some further styling we needed to adapt _compute_hierarchy_level to take it into account when calculating the increase level. So if the level is 0 or 1, the child will have a level of 3 either way.
- Removed some UPPERCASE column styling.
