feat: add view mounts, config, and terminal to container actions

[Siumauricio]

Summary

• Add a new View Mounts action to the container dropdown that displays volume and bind mounts in a clean table (type, source, destination, mode, read/write)
• Add View Config, View Mounts, and Terminal actions to compose containers tab, which previously only had logs and lifecycle actions
• Reuses existing docker inspect query — no new API endpoints needed

Greptile Summary

This PR adds View Mounts, View Config, and Terminal actions to the compose containers tab, and adds View Mounts to the standalone Docker containers table — all by reusing the existing api.docker.getConfig query with no new API endpoints. The implementation is consistent with the patterns already established by ShowContainerConfig and DockerTerminalModal.

Confidence Score: 5/5

• Safe to merge; the single finding is a minor UX polish item (missing loading indicator) that does not affect correctness.
• No P0 or P1 issues found. The new ShowContainerMounts component correctly reuses the existing getConfig query (React Query deduplicates it with ShowContainerConfig), nesting inside Radix dialogs is safe given the outer logs-dialog is always closed when the new modals are triggered, and the rest of the changes are straightforward drop-ins following established patterns.
• No files require special attention.

Missing loading state conflates "no mounts" with "still fetching"

When the dialog is opened before the query resolves, mounts is [] (the ?? [] fallback) and the "No mounts found" empty-state message is displayed — indistinguishable from a container that genuinely has no mounts. Consider checking isPending to show a loading indicator.

Suggested change

	{mounts.length === 0 ? (
	<div className="text-center text-muted-foreground py-8">
	No mounts found for this container.
	{isPending ? (
	<div className="text-center text-muted-foreground py-8">
	Loading mounts…
	</div>
	) : mounts.length === 0 ? (
	<div className="text-center text-muted-foreground py-8">
	No mounts found for this container.
	</div>

You'll need to destructure isPending from the useQuery call:

const { data, isPending } = api.docker.getConfig.useQuery(…);
