[18.0][MIG] stock_move_line_expiration_date_required: Migration to 18

[Andrii9090]

Straightforward migration to v18

I should make some minor changes.

In v18, there is no qty_done field in stock.move.line. According to this commit in Odoo 18, quantity is used

Now in Odoo not exist the view stock.view_stock_move_nosuggest_operations, this method action_show_details set a view stock.view_stock_move_operations

A method _get_move_lines in Odoo 18 no longer exists and has been replaced by the move_line_ids field (Row 246)

Great work @Andrii9090 !
The following tests have been executed successfully.

• Test 1: Verified mandatory manual expiration date for products with 0-day expiration time; system correctly blocked saving and validation until the date was filled.
• Test 2: Confirmed automatic expiration date calculation when expiration_time > 0; lines were populated with the correct computed date.
• Test 3: Checked serial generation with expiration_time = 0; serials were created without expiration date and validation was correctly blocked.
• Test 4: Confirmed automatic expiration date assignment during serial generation when expiration_time > 0; validation succeeded without manual input.
• Test 5: Ensured products without expiration control behaved normally; no date required and validation completed.
• Test 6: Validated mixed picking behavior; only caducable products blocked validation, and completing their expiration date allowed successful confirmation
