refactor(ui): drop the devices list's unreachable status filter

[gustavosbarreto]

The devices list still carries the code behind a filter no URL can reach. visibleTabs keeps only the accepted tab and an effect forces status back to accepted, so the pending and rejected column sets, their tabs and the accept/reject/remove dialog are unreachable, and the status constraint that validates the parameter has nothing left to validate.

This is #7048's 4b0b34300, kept as its own change because #7070 answered the issue a different way and left the dead code in place. Same removal, with one adjustment: the tab that used to filter by pending now links to the install keys list, where the decision is actually made, rather than to the /pending-devices page that PR proposed.

That leaves the list with one status and one way out of it, so the two links collapse into the single Install Keys link the list already had.

Code Review Complete

Reviewed 2 files across code quality, security, testing, language patterns, and architecture — no new issues found. The code looks good as-is.

The change is a clean removal of the unreachable status filter. Verified along the way:

• Removed hooks/components (useActionDialog, useDeviceActionRunner, ActionDialog) are still used by DeviceDetails/ContainerDetails — no dangling exports.
• All removed imports (useEffect, cn, UseActionDialogResult, etc.) and local symbols (VALID_STATUSES, statusTabs) are fully cleaned up.
• The columns useMemo dependency array matches its new body; the [hostnameColumn, ...detailColumns] destructure preserves the original column order.
• status: "accepted" is now a fixed literal, so dropping the URL status whitelist strictly narrows (not weakens) client input — confirmed by the updated tests.
• /install-keys is a real registered route; no /pending-devices route or ?status= consumer is left broken, and the cloud repo (Go-only) doesn't depend on this page.
