refactor: expose activated/discovered stats and device filters

[ShradhaGupta31]

Addresses: #1210

ADR: https://github.com/device-management-toolkit/console/wiki/API-contract-update-&-DB-query-mechanism-to-fetch-Device-Stats

• Add activatedCount and discoveredCount to the device stats response, and
• Add support ?activated=true / ?discovered=true filtering on the devices list endpoint
• Implements the Stats API exposure and Devices filtering across all three storage backends (Postgres, SQLite, MongoDB),
• Update OpenAPI/Fuego declarations and Postman collection entries.

Stats API responses:

$ curl -sk "https://localhost:8181/api/v1/devices/stats" -H "Authorization: Bearer $TOKEN" | jq .
{
  "totalCount": 10,
  "connectedCount": 0,
  "disconnectedCount": 0,
  "activatedCount": 6,
  "discoveredCount": 4
}

API to filter using Activated/Discovered
curl -sk "https://localhost:8181/api/v1/devices?discovered=true" -H "Authorization: Bearer $TOKEN" | jq .
curl -sk "https://localhost:8181/api/v1/devices?activated=true" -H "Authorization: Bearer $TOKEN" | jq .

Pull request overview

This PR extends the v1 Devices APIs to expose activated and discovered device state metrics in the stats response, and adds query-parameter filtering (?activated=true, ?discovered=true) to the devices list endpoint, wiring the behavior through the devices use case, repository interface, and both SQL + Mongo backends, with accompanying OpenAPI and Postman updates.

Changes:

• Add activatedCount and discoveredCount to GET /api/v1/devices/stats.
• Add ?activated=true / ?discovered=true filtering to GET /api/v1/devices.
• Implement repository + usecase support for activated/discovered queries and counts, including SQL and Mongo implementations, plus tests and API tooling updates.

rows.Err() is checked before iterating, and rows.Close() is deferred after that check. This could leave rows unclosed on error. Also, there is no rows.Err() check after the loop. Can we use the same pattern as GetByColumn and GetByTags?

[ShradhaGupta31]

Updated. Defer is now placed after all row fetch related checks are done.
