feat(27975): tag uniqueness and other validation updates

[vanch3d]

See https://hivemq.kanbanize.com/ctrl_board/57/cards/27975/details/

This PR adds client-side validation for device tags, ensuring they are unique per device but also across the Edge instance.

The PR also re-introduces other validations that wehnt missing due to the refactoring

• tag, topic and topic filter names are validated on input
• tag and topic filter references are through a select widget only (with options provided from list of candidates, no creation allowed)
• topic references is provided through the select widget that allows creation
