#2603 moved every run fact out of the conversation header into Conversation details. Cost went with it, so it now shows only when the details panel is open, in a list with runtime and tokens.

This puts the estimated cost back in the desktop title bar, next to the actions, with the same breakdown tooltip (opening below the bar). Desktop details drop their copy, which matches how location already works. Mobile hides the title bar, so cost stays in details there. conversationCost builds the cost metric for both places.

The usage card (cost and token tooltips) also gets a clearer type hierarchy: the title reads as a heading next to its total, the total drops from text-lg to text-base, and model-id labels use the same muted color as other row labels so only values stand out.

check / types and test / junior unit failed here because of a break on main, not this PR: web-batch-messages.test.ts imported webActorFromEmail, which #2630 removed (TS2305). #2643 fixed it on main as e35103a2d. Rebase onto main to clear those checks. ci / required failed only because those two did.
