[MIG] bemade_fsm to 18.0
Aside from fixing standard 17.0..18.0 stuff and fixing XML ID
references:
1. **Remove `_get_closed_stage_by_project()`**: This method is
obsolete - it was copied from base FSM but no longer exists in
18.0. Base system now uses `is_closed` field.
2. **Implement State Propagation**: Enhance the `write()` method
to propagate done/cancelled states to child tasks using `is_closed` field logic.
3. **Test Task Creation**: Thoroughly test the custom task creation logic
against base 18.0
All 56 tests are passing.
- Got rid of planned_date_begin and planned_date_end fields. Commented
out all related code for now. These were fields pending actual
feature development anyway.
- Added a product cateogory with income account and expense account to
the _generate_product common test method. This fixes an error where
Odoo complained about needing a due date for lines with account type
= 'asset_receivable'.
- Rewrote and refactored Task.action_fsm_validate to have it match with
code from industry_fsm in 16.0.
NOTE: This change depends on code pushed in:
- sale_workflow [16.0 ba7402471]
- odoo_addons [16.0 766cd78]
- PurchasedAddons [16.0 e5e9b7b]
