[FIX] mrp,purchase,repair,stock: cleanup of modifier refactoring

Minor cleanup after odoo/odoo#104741 thanks to edge-cases and the fun
complexity of logistics code. Fixes include:

- removing some readonly=False that were added on computed/stored fields
  that already have an inverse func or were already not readonly (i.e.
  redundant => cleanup)
- fixed visibility of qty to prod in subcontractor portal view of a MO
  (i.e. yay they know how much they're supposed to make again)
- remove unused imports
- adding back in readonly functionality of default dest of repair
  operation type (and removing the now useless field override that used
  to add in the readonly functionality)
- adding back in the `_set_product_qty` inverse function since it was
  probably removed by mistake (and is still important to have)

unrelated to viewpocolypse change, also fixed:
- mobile view of PO was for some reason allowing products to be changed
  in already confirmed/done POs, which could lead to some inconsistent
  data => made this consistent with existing desktop view behavior

closes odoo/odoo#133502
