Gandalf, Moria, and Arrest

It seems to me that Moria was as good a place as any to drop off the radar for a while. Remember that no one knew what Durin's Bane actually was, so the idea of entering its territory was not an assurance of anything.

Moria was a venture into the unknown, and with no news on Balin, even the dwarves were afraid of what became of his rule in Moria. The wolves may have been sent from Mordor, or they may have not. But the tracking and orders were directed from Mordor.

Why would Aragorn even contemplate arresting Gandalf when it appears that going through Mordor was not out of their equations anyway?

They did not know who or what was there, be it friend or foe. The impression you give is that they should never go there, and that Gandalf would have been forbidden to venture there by the Council, as if they knew they would encounter a Balrog.
