Prior to this commit, the dashboard was a table and there was unnecessary scss. This commit changes the table into the new bs5 grids and clean the scss files. In the portal view, a class(orders_label_text_align) that didn't affect the design was removed. task-2906527 closes odoo/odoo#95902 Signed-off-by: Adrien Dieudonné (adr) <adr@odoo.com>
