[FR] reduce general indentation space (between columns, after a toggle header etc.)

### Description

It is my opinion that appflowy is generally wasteful of horizontal space in page layout. For exemple, indentation (space) between multiple columns is overly large, making it difficult to display information on multiple columns (since so much space is "wasted").
This is also true of indentation inside of toggle lists or toggle header. The "paragraph indentation" is so pronounced that a lot of space is wasted.

If I create a toggle header and place toggle lists inside, about 1/3 of the horizontal space is now lost to indentation.
finally, the same could be said for bullet lists. Again, if I create a column and place a bullet list inside that column, the listed items might be barely visible because so much space is lost due to the indentation.

request : reduce app wide indentation by 1/2 at least.

### Impact

very hard to use certain formatting options because so much space is lost to indentations.
