[EDH-2444] Overlapping OS agreements can be created by extending the previous OS agreement

[EinarArro]

Steps

• Create new MP and GRID agreement
• Create first OS agreement with some validity period. In my case:

  {
  "agreementId": "einar-2024-05-15T13:18:37.347847+03:00-EST",
  "meterEic": "38ZGO-1000000L-7",
  "agreementType": "SUPPLY",
  "serviceProviderEic": "38X-EIN-OS-----J",
  "customerEic": "38X-AVP-ZW6700C6",
  "preliminaryTerminationFee": false,
  "commodityType": "ELECTRICITY",
  "validFrom": "2024-05-14T21:00:00Z",
  "validTo": "2024-05-31T21:00:00Z"
  }

• Create second OS agreement with different OPEN_SUPPLIER, so that it starts right after the first. In my case:

  {
  "agreementId": "einar-2024-05-15T13:20:08.578958+03:00-EST",
  "meterEic": "38ZGO-1000000L-7",
  "agreementType": "SUPPLY",
  "serviceProviderEic": "38X-EIN-ALL----B",
  "customerEic": "38X-AVP-ZW6700C6",
  "preliminaryTerminationFee": true,
  "commodityType": "ELECTRICITY",
  "validFrom": "2024-05-31T21:00:00Z"
  }

• Extend the validTo value of the first OS agreement so, that it should overlap with the second OS agreement. In my case:

  {
  "agreementId": "einar-2024-05-15T13:18:37.347847+03:00-EST",
  "meterEic": "38ZGO-1000000L-7",
  "agreementType": "SUPPLY",
  "serviceProviderEic": "38X-EIN-OS-----J",
  "customerEic": "38X-AVP-ZW6700C6",
  "preliminaryTerminationFee": false,
  "commodityType": "ELECTRICITY",
  "validFrom": "2024-05-14T21:00:00Z",
  "validTo": "2024-06-30T21:00:00Z"
  }

• Expected result (confirmed with Kajali) - activity should fail with error message
• Actual result - system creates overlapping SUPPLY agreements:
