[REF] mrp: update MO lock/unlock settings

This commit updates 4 features related to a MO being locked/unlocked.

1. Manufacturing orders are by default unlocked. A new configuration
setting has been added so users can set the default to be locked.
This setting only applies to new manufacturing orders after the setting
has been changed.

2. A MO now shows the same button options regardless if it is
locked/unlocked ('scrap', 'cancel', 'unreserve')

3. Workers can always change "Consumed Quantities"/"Produced" when
clicking on a component/finished product line unless state=Done and MO
is_locked. This includes adding new components/finished products.

4. Workers can now change "To Consume" quantity when clicking on a
component line, unlocked, and not in states 'Done' or 'Cancel'.

This is part of specification 6-Lock/Unlock of overall Editing in MO
form and backorders task.
