Subject: [PATCH] Persist updated values and apply saved dashboard parameters
 (#7570)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for saving dashboard parameters after clicking the Apply button. Parameters are applied in the following order: URL, dashboard parameters, query parameters.

Persist the queued values only when “Done Editing” is clicked, keeping Query and Dashboard editors aligned.
