fix(tui): render console org load errors inline

[rekram1-node]

Problem

The "Switch org" dialog (DialogConsoleOrg) loads orgs via console.listOrgs({}, { throwOnError: true }). On failure the resource rejects and enters an errored state; reading orgs() inside the options/current memos then re-throws, which tears down the dialog instead of showing anything actionable.

This is the same failure class fixed for the move dialog in #32241.

Fix

Catch the failure into a loadError signal so the rejected resource never reaches the memos, and render an inline error inside the dialog instead of crashing. Reuses the emptyView slot added to DialogSelect in #32241:

• renderFilter={false}, locked, and options={[]} in the error state
• red bold "Could not load orgs" title + muted error message
• esc dismisses; the dialog keeps the same shell

No source signal / refetch here, so the load is single-shot: success renders the list, failure renders the inline error.

Testing

• bun typecheck and bun prettier --check pass from packages/tui.
• Verified with termctrl using a forced fetch failure: compact inline error in the same dialog shell, filter hidden, esc dismisses cleanly, no crash.
