[IMP] partner_statement: remove "blocked" feature

If someone comes from v17 or older Odoo versions, and they still have "blocked" lines, there are three options for them:

- Develop glue module with another module that contains "blocked" field.
- Don't use this commit.
- Solve the "blocked" lines.

Good luck!
