Answer 1

You forgot to indent your code block

# DO NOT DO THIS
class salesapproval_sale_order(osv.Model):
_inherit = 'sale.order'
# code

# DO THIS
class salesapproval_sale_order(osv.Model):
    _inherit = 'sale.order'
    # code

Answer 2

The error tells you exactly what is wrong. You have an indentation error in the salesapproval.py file at the line _inherit = 'sale.order'

Everything within class salesapproval_sale_order should be indented one block.

class salesapproval_sales_order(osv.Model):
    _inherit = 'sale.order'
    ....
