Support user-friendly version selection via URL parameters

[ryanbasic1]

Currently, the URL preselection feature requires using internal version_id values (which are long hash-based identifiers, e.g. ardupilot-92b0cd7...).

While this works correctly, it is not very user-friendly when:

Sharing links with others
Manually constructing URLs
Testing or debugging configurations

Suggestion:
Allow alternative, user-friendly query parameters such as:

?vehicle_id=copter&version=stable
?vehicle_id=rover&version=4.6.3

These values could be internally mapped to the corresponding version_id.
Expected Behavior:

If version is provided:
stable → map to latest stable version
4.6.3 → map to matching version
If mapping fails → fallback to existing behavior or show warning

Benifits = 1) Easier sharing of build Configuration , improved UX , More intuitive URL usage
