Sale Rental Maintenance

Rental Sale Maintenance is an integration module that ensures rental products cannot be rented and maintained at the same time. It acts as a bridge between rental_sale_product and rental_maintenance.

The module automatically checks overlapping schedules between rental sale orders and maintenance requests, ensuring resource availability and preventing conflicts.

• Rental → Maintenance: A product already rented cannot be selected for maintenance if rental dates overlap.
• Maintenance → Rental: A product under maintenance cannot be selected in new rental orders during the maintenance period.

The module extends both sale.order.line and maintenance.request:

• Checks active rentals before confirming maintenance requests.
• Checks active maintenances before confirming rental sale orders.
• All datetime comparisons are done in UTC; user-facing warnings are shown in the user's timezone.

Example:
Product: Bike A
Rental:  2025-10-16 09:00 → 2025-10-17 09:00
Maintenance: 2025-10-16 08:00 → 2025-10-16 12:00

Result:
When scheduling maintenance, Odoo shows:
"Bike A is currently rented from 2025-10-16 09:00 to 2025-10-17 09:00.
Maintenance cannot be scheduled in this period."
